int mini_regex(const char *text, const char *pattern)

NAME
mini_regex - look alike regex functions

SYNOPSIS
#include "mini_regex.h"
int mini_regex(const char *text, const char *pattern)

DESCRIPTION
mini_regex() is used to match a null-terminated string against a null-terminated pattern.

RETURN VALUE
mini_regex() returns zero for a successful match or 0 for failure.

CAVEATS
Can't support a pattern that is not exactly 5 characters long
can be very dangerous if pattern is poorly written.
Segfault if parameters is NULL.

EXAMPLES

   #include <stdio.h>
   #include "mini_regex.h"

   int main(void)
   {
          size_t       t;
          size_t       p;
          const char *pattern[] = 
          {
                 "[^^^][0-9]\0",
                 "[0-9]\0",
                 NULL
          };
          const char *text[] =
          {
                 "   1234\0",
                 "1232222\0",
                 NULL
          };
          p = 0;
          while (pattern[p])
          {
                 t = 0;
                        printf("%s\n", pattern[p]);
                 while (text[t])
                 {
                        if (mini_regex(text[t], pattern[p]))
                               printf("OK:\t%s\n", text[t]);
                        else
                               printf("NOK:\t%s\n", text[t]);
                        t++;
                 }
                 p++;
          }
          return (0);
   }
