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.SEE ALSO
