re_comp
re_comp(3C) Standard C Library Functions re_comp(3C)
NAME
re_comp, re_exec - compile and execute regular expressions
SYNOPSIS
#include <re_comp.h>
char *re_comp(const char *string);
int re_exec(const char *string);
DESCRIPTION
The re_comp() function converts a regular expression string (RE) into an internal form suitable for pattern matching. The re_exec() func-
tion compares the string pointed to by the string argument with the last regular expression passed to re_comp().
If re_comp() is called with a null pointer argument, the current regular expression remains unchanged.
Strings passed to both re_comp() and re_exec() must be terminated by a null byte, and may include NEWLINE characters.
The re_comp() and re_exec() functions support simple regular expressions, which are defined on the regexp(5) manual page. The regular
expressions of the form {m}, {m,}, or {m,n} are not supported.
RETURN VALUES
The re_comp() function returns a null pointer when the string pointed to by the string argument is successfully converted. Otherwise, a
pointer to one of the following error message strings is returned:
No previous regular expression
Regular expression too long
unmatched (
missing ]
too many () pairs
unmatched )
Upon successful completion, re_exec() returns 1 if string matches the last compiled regular expression. Otherwise, re_exec() returns 0 if
string fails to match the last compiled regular expression, and -1 if the compiled regular expression is invalid (indicating an internal
error).
ERRORS
No errors are defined.
USAGE
For portability to implementations conforming to X/Open standards prior to SUS, regcomp(3C) and regexec(3C) are preferred to these func-
tions. See standards(5).
