Reentrant function to retrieve tokens from a string. allegro game programming library.
#include <allegro.h>
char *ustrtok_r(char *s, const char *set, char **last);
Reentrant version of ustrtok. The `last' parameter is used to keep track of where the parsing is up to and must be a pointer to a char * variable allocated by the user that remains the same while parsing the same string. Example:
char *word, *last; char string[]="some-words with dashes"; char *temp = ustrdup(string); word = ustrtok_r(string, " -", &last); while (word) { allegro_message("Found `%s'\n", word); word = ustrtok_r(NULL, " -", &last); } free(temp);
Returns a pointer to the token, or NULL if no more are found. You can free the memory pointed to by `last' once NULL is returned.
