Description David Gardner 2003-10-12 21:10:23 UTC

The fnmatch function doesn't seem to like any of the character classes that are listed in the re_format man page. I ssh'ed to a linux box to check this and the character classes behaved the way I expected them to.

Fix: 

fnmatch seems to like the expression "[A-Za-z]" which is equivelent to "[[:alpha:]]".
How-To-Repeat: 

#include <iostream>
#include <fnmatch.h>
void main () {  
  int result = fnmatch ("[[:alpha:]]","x", FNM_PATHNAME);
  if (result == FNM_NOMATCH)
    cout << "failed" << endl;
  else
    cout << "passed" << endl;
}

I agree that this behaviour is incorrect and have documented it in the 
fnmatch(3) manual page.

Canonicalize assignment.
Comment 6 Jörg Schilling 2017-08-03 17:12:03 UTC
It is more than [:alpha:]....

it is:
  [: :] character class 
  [= =] equivalence character class 
  [. .] collation symbol 

Given that the bugreport is 14 years old, is there a chance that this will be implemented in a predictable time?

I am asking this because I am currently taking the FreeBSD libc i18n code and integrating it into libc from OpenSolaris (SchilliX) and I would like to get something that could pass the POSIX certification tests.
Comment 7 Jörg Schilling 2017-08-04 16:22:42 UTC
BTW: bin/sh/expand.c implements [:alpha:] but not the equivalence class and not the collation symbol.

It may still help how to implement things...
