ustrtok

ustrtok(3alleg4)						  Allegro manual						  ustrtok(3alleg4)

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'
", word);
	     word = ustrtok(NULL, " -");
	  }
	  free(temp);

RETURN VALUE

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