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(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.
ATTRIBUTES
Multithreading (see pthreads(7))
The
re_comp() and
re_exec() functions are not thread-safe.
CONFORMING TO
4.3BSD.
NOTES
These functions are obsolete; the functions documented in
regcomp(3) should be used instead.
