Compile a regular expression
#include <unix.h> char *re_comp( char *s );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The re_comp() function converts a regular expression string (RE) into an internal form suitable for pattern matching. Use this function with re_exec().
The re_comp() and re_exec() functions support simple regular expressions. The regular expressions of the form \{m\}, \{m,\}, or \{m,n\} aren't supported.
NULL if the string pointed to by s was successfully converted. Otherwise, a pointer to one of the following error message strings is returned:
