Синопсис (Synopsis)

#define _REGEX_RE_COMP
       #include <sys/types.h>
       #include <regex.h>

       char *re_comp(const char *regex);
       int re_exec(const char *string);

Описание (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.

---

Возвращаемое значение (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.
