Description:
Change the current position in the file. You can either seek forward or backward through the file.
(File:handle, position, whence)
| handle | The file handle to use. Returned by fopen. |
| position | The new position in the file, relative to the parameter whence (see below). |
| whence | The starting position to which parameter position relates. |
Return Values:
The new position; relative to the start of the file.
Whences
| seek_start | Set the file position relative to the start of the file (the position parameter must be positive). |
| seek_current | Set the file position relative to the current file position: the position parameter is added to the current position. |
| seek_end | Set the file position relative to the end of the file (parameter position must be zero or negative). |
Example Usage:
// Open "file.txt" in "read only" mode new File:handle = fopen("file.txt", io_read); // If "file.txt" is open if(handle) { // Success // Jump to the 1st byte of "file.txt", and print its position printf("Begin of file position: %d", fseek(handle, 0, seek_start)); // Jump to the last byte of "file.txt", and print its position printf("End of file position: %d", fseek(handle, 0, seek_end)); // Jump to the same byte of "file.txt", and print its position printf("Currrent file position: %d", fseek(handle, 0, seek_current)); // Close "file.txt" fclose(handle); } else { // Error print("Failed to open \"file.txt\"."); }
