| 36 | DESCRIPTION |
||
| 37 | The < |
||
| 38 | null-terminated string, <<*<[source]>>>. These tokens are delimited |
||
| 39 | in the string by at least one of the characters in <<*<[delimiters]>>>. |
||
| 40 | The first time that < |
||
| 41 | specified; subsequent calls, wishing to obtain further tokens from |
||
| 42 | the same string, should pass a null pointer instead. The separator |
||
| 43 | string, <<*<[delimiters]>>>, must be supplied each time and may |
||
| 44 | change between calls. |
||
| 45 | |||
| 46 | The < |
||
| 47 | subsequent token in the string, after replacing the separator |
||
| 48 | character itself with a null character. When no more tokens remain, |
||
| 49 | a null pointer is returned. |
||
| 50 | |||
| 51 | The < |
||
| 52 | a pointer to placeholder <<*<[lasts]>>> must be supplied by the caller. |
||
| 53 | |||
| 54 | The < |
||
| 55 | a pointer to the string pointer must be supplied <<<[source_ptr]>>> and |
||
| 56 | the function does not skip leading delimiters. When the string starts |
||
| 57 | with a delimiter, the delimiter is changed to the null character and |
||
| 58 | the empty string is returned. Like < |
||
| 59 | <<*<[source_ptr]>>> is updated to the next character following the |
||
| 60 | last delimiter found or NULL if the end of string is reached with |
||
| 61 | no more delimiters. |
||
