re_comp(3) Library Functions Manual re_comp(3)
re_comp, re_exec - BSD regex functions
Standard C library (libc, -lc)
#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);
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.
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.

None.
4.3BSD. These functions are obsolete; the functions documented in regcomp(3) should be used instead.
