ustrtok_r man page

ustrtok_r — 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);

Return Value

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.
