Description

pos

Desired new pointer position. Supplied value will be corrected if out of range. For the files of 0 size (see fd.filesize), the pointer may only have one value — 0. If the file has non-zero size, the pointer can be between 1 and fd.filesize+1. "1" is the position of the first byte of the file. The last existing byte of the file is at position equal to the value of fd.filesize. "Fd.filesize+1" is the position at which new data can be added to the file.
