   re_comp    ( 3 )

функции регулярных выражений BSD (BSD regex functions)

Имя (Name)

re_comp, re_exec - BSD regex functions

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.
