The fseek function in C is a versatile tool that allows you to move the file pointer within a file based on specified offset values relative to different positions. It can seek from three distinct locations:

  1. The beginning of the file, allowing you to set the file pointer to any position starting from the start.
  2. The current location, which lets you adjust the pointer relative to where you are at that moment in the file.
  3. The end of the file, enabling you to position the pointer starting from the end and moving backwards.

This capability of fseek to operate based on all three reference points — the beginning, the current position, and the end — is what makes it particularly useful for file manipulation. By specifying an offset and a reference point, you can navigate through a file flexibly and efficiently. Understanding this functionality is critical for tasks such as reading, writing, or updating data in files, making the correct choice that includes all these possible reference points.
