- DESCRIPTION:
- The function fread reads nmemb elements of data, each size bytes long,
- from the stream pointed to by stream, storing them at the location
- given by ptr.
-
- RETURN VALUE:
- return the number of items successfully read or written (i.e.,
- not the number of characters). If an error occurs, or the
- end-of-file is reached, the return value is a short item count
- (or zero).
-
- We do not distinguish between end-of-file and error, and callers
- must use feof(3) and ferror(3) to determine which occurred.

- Like fseek(3) and in fact may be the same.
-
- This function sets the file position indicator for the stream
- pointed to by stream. The new position, measured in bytes, is obtained
- by adding offset bytes to the position specified by whence. If whence
- is set to SEEK_SET, SEEK_CUR, or SEEK_END, the offset is relative to
- the start of the file, the current position indicator, or end-of-file,
- respectively. A successful call to the fseek function clears the end-
- of-file indicator for the stream and undoes any effects of the
- ungetc(3) function on the same stream.
-
- RETURN VALUE
- Upon successful completion, return 0,
- Otherwise, -1 is returned and the global variable errno is set to indi-
- cate the error.
