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.
