Description G. Paul Ziemba 2008-12-01 08:30:01 UTC
asclock dies immediately with error "not enough free color cells"

Fix: "not enough free color cells" is erroneously printed for any error returned by XpmCreatePixmapFromData, e.g., corrupt xpm data.

The actual cause of the error in this case was a buffer overrun when constructing the LED pixmap data.

Attached patch addresses several things:
1 - buffer overrun
2 - simplified bizarre method of printing with format %04X
3 - error messages match actual errors from XpmCreatePixmapFromData
4 - missing error test for one call to XpmCreatePixmapFromData


Patch attached with submission follows:
How-To-Repeat: $ asclock
not enough free color cells
