std::strtok
| Defined in header <cstring>
|
||
| char* strtok( char* str, const char* delim ); |
||
Finds the next token in a null-terminated byte string pointed to by str. The separator characters are identified by null-terminated byte string pointed to by delim.
If str != NULL, the function searches for the first character which is not separator. This character is the beginning of the token. Then the function searches for the first separator character. This character is the end of the token. Function terminates and returns NULL if end of str is encountered before end of the token is found. Otherwise, a pointer to end of the token is saved in a static location for subsequent invocations. This character is then replaced by a NULL-character and the function returns a pointer to the beginning of the token.
If str == NULL, the function continues from where it left in previous invocation. The behavior is the same as if the previously stored pointer is passed as str.
