   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.
