char * strtok_r

char * strtok_r(char *, const char *, char **)

strtok_r parses string into tokens. The first call to strtok_r should have string as its first argument. Subsequent calls should have the first argument set to NULL. If a token ends with a delimiter, this delimiting character is overwritten with a '\0' and a pointer to the next character is saved for the next call to strtok_r. The delimiter string delim may be different for each call. last is a user allocated char* pointer. It must be the same while parsing the same string. strtok_r is a reentrant version of strtok().


The strtok_r() function returns a pointer to the next token or NULL when no more tokens are found.
