short isextlower (short c); |
Checks whether a character is a lowercase, including foreign ones.
isextlower returns nonzero if c is a lowercase letter, either ordinary ('a' to 'z') or foreign one (see isfrgnlower), otherwise it returns zero. It is an inline function which is implemented using GNU C smart macros, which expands to a medium-sized code.
