write to part of a file
This command writes to part of a file. It writes the data buffer content to the file path starting at offset
offset.
This command implements the pwrite(2) system call, and like that system call it may not write the full data requested. The return value is the number of bytes that were actually written to the file. This could even be 0, although short writes are unlikely for regular files in ordinary circumstances.
