write to part of a device
This command writes to part of a device. It writes the data buffer content to device 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 (although short writes to disk devices and partitions are probably impossible with standard Linux kernels).
See also pwrite.
