#include "sflstr.h"
char *
strprefix (
    const char *string,
    const char *delims)

Synopsis

Looks for one of the delimiter characters in the string; if found, returns a string that contains the text up to that delimiter. If not found, returns NULL. The returned string can be zero or more characters long followed by a null byte. It is allocated using the mem_alloc() function; you should free it using mem_free() when finished.

{
    const char
        *nextch;
    char
        *token;
    int
        token_size;

    ASSERT (string);
    ASSERT (delims);

    for (nextch = string; *nextch; nextch++)
      {
        if (strchr (delims, *string))   /*  Is next character a delimiter    */
          {
            token_size = (int) (nextch - string);
            token = mem_alloc (token_size + 1);
            if (token == NULL)
                return (NULL);          /*  Not enough memory - fail         */
            memcpy (token, string, token_size);
            token [token_size] = 0;
            return (token);
          }
      }
    return (NULL);
}
