Break a string into tokens (reentrant)
#include <string.h> char* strtok_r( char* s, const char* sep, char** state );
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The function strtok_r() breaks the string s into a sequence of tokens, each of which is delimited by a character from the string pointed to by sep.
In the first call to strtok_r(), s must point to a null-terminated string, sep points to a null-terminated string of separator characters, and state is ignored. The strtok_r() function returns a pointer to the first character of the first token, writes a NULL character into s immediately following the returned token, and updates state.
In subsequent calls, s must be a NULL pointer and state must be unchanged from the previous call so that subsequent calls will move through the string s, returning successive tokens until no tokens remain. The separator string sep may be different from call to call. When no tokens remain in s, a NULL pointer is returned.
|You might want to keep a copy of the original string because strtok_r() is likely to modify it.|
A pointer to the token found, or NULL if no token was found.
