ISCSYM(3) Library Functions ISCSYM(3)
NAME
iscsym - tell whether given character could be found in a C
symbol
SYNOPSIS
#include <edlib.h>
int iscsym(c)
char c;
DESCRIPTION
Iscsym tells whether it is possible that the given character
could appear in a C symbol. A C symbol might be the name of a
variable, structure, reserved word or a function. Not all
characters that are valid in a C symbol may be the first
character of an identifier in most implementations of C. In
most versions, the characters allowed after the first character
are the upper and lower case alphabetic characters, the digits
'0' to '9' and the underscore (_).

BUGS
This function depends on the C compiler used, and thus the
characters that are valid in a C symbol may be different, even
on the same machine.
