!!NAME


re_comp, re_exec - BSD regex functions
!!SYNOPSIS


__#include __


__char *re_comp(char *__''regex''__);
int re_exec(char *__''string''__);__
!!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''.
!!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.
