RE_COMP(3) Linux Programmer's Manual RE_COMP(3)NAME
re_comp, re_exec - BSD regex functions
SYNOPSIS
#define _REGEX_RE_COMP
#include <sys/types.h>
#include <regex.h>
char *re_comp(const char *regex);
int re_exec(const char *string);
DESCRIPTIONre_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 VALUEre_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.
