re_comp, re_exec - BSD regex functions
#define _REGEX_RE_COMP
#include <sys/types.h>

char *re_comp(const char
*regex
);
int re_exec(const 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
.
For an explanation of the terms used in this section, see attributes(7).

These functions are obsolete; the functions documented in regcomp(3) should be used instead.
