mongoc_gridfs_file_seek − mongoc_gridfs_file_seek()
int mongoc_gridfs_file_seek (mongoc_gridfs_file_t *file, int64_t delta, int whence);
• |
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. |
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):
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.
Returns 0 if successful; otherwise −1 and errno is set.
