mongoc_gridfs_file_seek - Man Page
Synopsis
int mongoc_gridfs_file_seek (mongoc_gridfs_file_t *file, int64_t delta, int whence);
Parameters
- file: A mongoc_gridfs_file_t.
- delta: The amount to move the file position. May be positive or negative.
- whence: One of SEEK_SET, SEEK_CUR or SEEK_END.
Description
Adjust the file position pointer in the given file by delta, starting from the position whence. The whence argument is interpreted as in fseek(2):
| SEEK_SET | Set the position relative to the start of the file. |
| SEEK_CUR | Move delta relative to the current file position. |
| SEEK_END | Move delta relative to the end of the file. |
On success, the file's underlying position pointer is set appropriately. On failure, the file position is NOT changed and errno is set to indicate the error.
Errors
| EINVAL | whence is not one of SEEK_SET, SEEK_CUR or SEEK_END. |
| EINVAL | The resulting file position would be negative. |
Returns
Returns 0 if successful; otherwise -1 and errno is set.
