NAME

ustrtok - Retrieves tokens from a string. Allegro game programming library.

SYNOPSIS

#include <allegro.h>

char *ustrtok(char *s, const char *set);

DESCRIPTION

This function retrieves tokens from `s' which are delimited by characters from `set'. To initiate the search, pass the string to be searched as `s'. For the remaining tokens, pass NULL instead. Warning: Since ustrtok alters the string it is parsing, you should always copy the string to a temporary buffer before parsing it. Also, this function is not re-entrant (ie. you cannot parse two strings at the same time). Example:

   char *word;


   char string[]="some-words with dashes";


   char *temp = ustrdup(string);


   word = ustrtok(temp, " -");


   while (word) {


      allegro_message("Found `%s'\n", word);


      word = ustrtok(NULL, " -");


   }


   free(temp);

RETURN VALUE

Returns a pointer to the token, or NULL if no more are found.
