[;1m pwrite(IoDevice, LocBytes)[0m
Performs a sequence of [;;4mpwrite/3[0m in one operation, which is more
efficient than calling them one at a time. Returns [;;4mok[0m or [;;4m[0m
[;;4m{error, {N, Reason}}[0m, where [;;4mN[0m is the number of successful
writes done before the failure.
When positioning in a file with other [;;4mencoding[0m than [;;4mlatin1[0m,
caution must be taken to set the position on a correct character
boundary. For details, see [;;4mposition/2[0m.
[;1m pwrite(IoDevice, Location, Bytes)[0m
Combines [;;4mposition/2[0m and [;;4mwrite/2[0m in one operation, which is
more efficient than calling them one at a time.
[;;4mLocation[0m is only allowed to be an integer for [;;4mraw[0m and [;;4mram[0m
modes.
The current position of the file after the operation is undefined
for [;;4mraw[0m mode and unchanged for [;;4mram[0m mode.
When positioning in a file with other [;;4mencoding[0m than [;;4mlatin1[0m,
caution must be taken to set the position on a correct character
boundary. For details, see [;;4mposition/2[0m.
