NAME
re_comp, re_exec - BSD regex functions
SYNOPSIS
#include <regex.h>
char *re_comp(char *regex);
int re_exec(char *string);
DESCRIPTION
re_comp
is used to compile the null-terminated regular expression pointed to by
regex.
The compiled pattern occupies a static area, the pattern buffer,
which is overwritten by subsequent use of
re_comp.
If
regex
is
NULL,
no operation is performed and the pattern buffer's contents are not
altered.
re_exec
is used to assess whether the null-terminated string pointed to by
string
matches the previously compiled
regex.
RETURN VALUE
re_comp
returns
NULL
on successful compilation of
regex
otherwise it returns a pointer to an appropriate error message.
re_exec
returns 1 for a successful match, zero for failure.
