re_comp, re_exec — BSD regex functions
#define _REGEX_RE_COMP #include <sys/types.h> #include <regex.h>
char
*re_comp( |
char * | regex); |
int
re_exec( |
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.
