>-This manual page documents convenience routines for handling symbol
>-tables.
>-Two flavors of symbol tables are supported:
>-.Bl -bullet -compact
>-.It
>-.Dq Regular
>-symbol tables supporting insertion, deletion and lookup of entries by
>-name or by value, sorting of entries, and stepping through entries in
>-the table's current traversal order.
>-.It
>-.Dq ELF-centric
>-symbol tables support additional operations for conversions to and
>-from the symbol table format understood by
>-.Lb libelf .
>-.El
>-The default traversal order for a symbol table is the order in which
>-entries were inserted into it.
>-This traversal order may be changed using function
>-.Fn elftc_symbol_table_sort .
>-.Ss Operations on Regular Symbol Tables
>-Regular symbol tables use symbols that are subtypes of
>-.Vt Elftc_Symbol ,
>-as described in the section
>-.Sx "Structure of a Symbol Table Entry"
>-below.
>-.Pp
>-Function
>-.Fn elftc_symbol_table_count
>-returns the number of entries currently in the symbol table.
>-.Pp
>-Function
>-.Fn elftc_symbol_table_create
>-creates a new, empty symbol table.
>-The argument
>-.Ar entrysize
>-specifies the size of each symbol table entry, as described
>-in the section
>-.Sx "Structure of a Symbol Table Entry"
>-below.
>-The argument
>-.Ar sizehint
>-specifies the expected number of symbol table entries.
>-If
>-.Ar sizehint
>-is zero, an implementation-defined default will be used.
>-.Pp
>-Function
>-.Fn elftc_symbol_table_create_nested
>-creates a symbol table whose search scope nests inside that of a
>-parent symbol table.
>-The argument
>-.Ar parent
>-specifies the parent symbol table to nest under.
>-The argument
>-.Ar sizehint
>-specifies the expected number of symbol table entries.
>-If
>-.Ar sizehint
>-is zero, an implementation-defined default will be used instead.
>-.Pp
>-The function
>-.Fn elftc_symbol_table_delete_name
>-removes the symbol entry named by the argument
>-.Ar name
>-from the symbol table specified by argument
>-.Ar table ,
>-according to the rules described in section
>-.Sx "Symbol Search Rules" .
>-.Pp
>-The function
>-.Fn elftc_symbol_table_delete_entry
>-removes the symbol table entry specified by argument
>-.Ar entry
>-from the symbol table specified by argument
>-.Ar table .
>-.Pp
>-Function
>-.Fn elftc_symbol_table_destroy
>-is used to destroy a symbol table and free up its internal
>-resources.
>-.Pp
>-The function
>-.Fn elftc_symbol_table_insert
>-inserts a symbol entry for the name specified by argument
>-.Ar symbolname
>-into the symbol table specified by argument
>-.Ar table ,
>-returning a pointer to a symbol table entry.
>-The argument
>-.Ar status
>-should point to a location that will be updated with one of
>-the following values:
>-.Bl -tag -width indent -compact -offset indent
>-.It Dv ELFTC_INSERT_ERROR
>-An error occurred during insertion of the symbol.
>-.It Dv ELFTC_INSERT_EXISTING
>-The name in argument
>-.Ar symbolname
>-was already in the symbol table, and a pointer to the existing
>-symbol table entry is being returned.
>-.It Dv ELFTC_INSERT_NEW
>-A new symbol table entry was allocated for the symbol name
>-in
>-.Ar symbolname .
>-The application will need to initialize the application-specific
>-fields of the symbol table entry.
>-.El
>-Insertion obeys the scoping rules described in section
>-.Sx "Symbol Search Rules" .
>-.Pp
>-The function
>-.Fn elftc_symbol_table_iterate
>-iterates over the symbol table specifed by argument
>-.Ar table ,
>-applying the function pointed to by argument
>-.Ar iterfn
>-to each symbol table entry.
>-The return value from the function
>-.Ar iterfn
>-controls progress of the iteration:
>-.Bl -tag -width indent -compact -offset indent
>-.It Dv ELFTC_ITERATE_ABORT
>-Terminates the iteration.
>-.It Dv ELFTC_ITERATE_CONTINUE
>-Iteration will continue on to the next element in the symbol table.
>-.El
>-Argument
>-.Ar cookie
>-will be passed to each invocation of
>-.Ar iterfn ,
>-and may be used to track persistent state.
>-The ordering of symbol table entries presented to function
>-.Ar iterfn
>-is not defined.
>-The behavior of the iteration is undefined if
>-.Ar iterfn
>-adds or deletes symbol entries from a symbol table that currently
>-being iterated through.
>-.Pp
>-Function
>-.Fn elftc_symbol_table_lookup
>-returns the symbol entry corresponding to the name of the symbol
>-in argument
>-.Ar symbolname .
>-.Pp
>-Function
>-.Fn elftc_symbol_table_lookup_value
>-returns the symbol entry that has a
>-.Va sym_value
>-field that is closest to the value specified in argument
>-.Ar value .
>-The argument
>-.Ar table
>-should point to a symbol table, that has been sorted
>-by a prior call to
>-.Fn elftc_symbol_table_sort .
>-The argument
>-.Ar searchflags
>-can be a combination of the following flags:
>-.Bl -tag -width indent -compact -offset indent
>-.It Dv ELFTC_SEARCH_FORWARD
>-Find the symbol entry with the next higher value in its
>-.Va sym_value
>-field.
>-.It Dv ELFTC_SEARCH_BACKWARD
>-Find the symbol entry with next lower value in its
>-.Va sym_value
>-field.
>-.El
>-If both
>-.Dv ELFTC_SEARCH_FORWARD
>-and
>-.Dv ELFTC_SEARCH_BACKWARD
>-are specified, then this function will return the symbol that is
>-closest to the argument
>-.Ar value .
>-.Pp
>-Function
>-.Fn elftc_symbol_table_replace
>-moves the symbol table entry pointed to by argument
>-.Ar sym2
>-into the traversal position for the entry pointed to by
>-.Ar sym1 ,
>-and implicitly deletes the entry pointed to by argument
>-.Ar sym1 .
>-Argument
>-.Ar table
>-should point to a valid symbol table.
>-.Pp
>-Function
>-.Fn elftc_symbol_table_sort
>-is used to define an ordering of symbol entries in a symbol
>-table.
>-This ordering will be associated with the symbol table till the next
>-call to function
>-.Fn elftc_symbol_table_insert ,
>-.Fn elftc_symbol_table_delete_name
>-or
>-.Fn elftc_symbol_table_delete_entry .
>-The argument
>-.Ar cmpfn
>-should point to a function that compares two symbol entries pointed
>-to by
>-.Ar s1
>-and
>-.Ar s2
>-and returns -1, 0, or 1, depending whether
>-.Ar s1
>-is less, equal to, or greater than
>-.Ar s2
>-respectively.
>-.Pp
>-Function
>-.Fn elftc_symbol_table_step
>-is used to step to the next symbol in a sorted symbol table.
>-Argument
>-.Ar table
>-should point to a symbol table.
>-The argument
>-.Ar cursym
>-specifies the current symbol.
>-The argument
>-.Ar direction
>-specifies the direction to step:
>-.Bl -tag -width indent -compact -offset ident
>-.It Dv ELFTC_STEP_NEXT
>-Return the symbol which follows the argument
>-.Ar cursym
>-in the current traversal order.
>-If argument
>-.Ar cursym
>-is NULL, return the first symbol in the current
>-traversal order.
>-.It Dv ELFTC_STEP_PREVIOUS
>-Return the symbol which precedes the argument
>-.Ar cursym
>-in the current traversal order.
>-If argument
>-.Ar cursym
>-is NULL, return the last symbol in the current
>-traversal order.
>-.El
>-.Ss Operations on ELF-centric symbol tables
>-ELF-centric symbol tables use symbols that are subtypes of
>-.Vt Elftc_Elf_Symbol ,
>-as described in the section
>-.Sx "Structure of a Symbol Table Entry"
>-below.
>-.Pp
>-In addition to the operations on regular symbol tables listed above,
>-these symbol tables may be used with the following additional
>-functions.
>-.Pp
>-The function
>-.Fn elftc_elf_symbol_table_from_section
>-builds a symbol table from the contents of an ELF section.
>-The argument
>-.Ar symscn
>-should reference an ELF section of type
>-.Dv SHT_SYMTAB
>-or
>-.Dv SHT_DYNSYM .
>-The argument
>-.Ar strscn
>-should reference an ELF section of type
>-.Dv SHT_STRTAB
>-containing the string table associated wit section
>-.Ar symscn .
>-.Ss Structure of a Symbol Table Entry
>-The symbol tables managed by
>-.Lb libelftc
>-are collections of symbol table entries.
>-Each entry should be a subtype of one of the
>-.Vt Elftc_Symbol
>-or
>-.Vt Elftc_Elf_Symbol
>-types.
>-In other words, each entry should have an
>-.Vt Elftc_Symbol
>-or
>-.Vt Elftc_Elf_Symbol
>-structure as its first member, before any application specific
>-fields.
>-For example:
>-.Bd -literal -offset indent
>-struct _MySymbol {
>-	Elftc_Symbol	sym_base;
>-	... other application-specific fields ...
>-};
>-.Ed
>-.Pp
>-The size of the combined entry is indicated to the library
>-at the time of creating a new symbol table.
>-Applications may then cast the returned pointers from these
>-routines to the appropriate type:
>-.Bd -literal -offset indent
>-struct _MySymbol *mysym;
>-
>-mysym = (struct _MySymbol *) elftc_symbol_table_lookup(table,
>-	    name);
>-.Ed
>-.Pp
>-The
>-.Vt Elftc_Symbol
>-type has two public fields:
>-.Bl -tag -width ".Va sym_value" -compact -offset indent
>-.It Va sym_name
>-Points to a NUL-terminated string containing the symbol's name.
>-The application should not change the value of this field.
>-.It Va sym_value
>-The value associated with this symbol.
>-This field is entirely under the application's control.

>-The application should not change the value of this field.
>-.It Va sym_elf
>-A structure of type
>-.Vt Gelf_Sym

>-This field is entirely under the application's control.
>-.El
>-.Ss Symbol Search Rules
>-During lookups, symbols are looked up first in the symbol table passed in
>-to the
>-.Fn elftc_symbol_table_lookup
>-function.
>-If the specified symbol is not found, and if the symbol table has a
>-parent, then the search continues recursively up the chain of parent
>-symbol tables till either a matching symbol is found or till there are
>-no more parent symbol tables to search in.
>-.Pp
>-Insertions and deletion only work on the specified symbol table and
>-do not recurse into parent symbol tables.
