Bsd regex functions
Usage
#define _REGEX_RE_COMP #include <sys/types.h> #include <regex.h>
[[deprecated]] char *re_comp(const char *regex); [[deprecated]] int re_exec(const char *string);
Library
Standard C library (libc, -lc)
Overview
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.
