Re^2: write/syswrite return value differences by Eliya (Vicar) on Nov 24, 2011 at 18:07 UTC
I suppose the OP is talking about the IO::Handle method `write`, and was probably misled by the wording 'is like "write" found in C': $io->write ( BUF, LEN [, OFFSET ] ) This "write" is like "write" found in C, that is it is the opposite of read. The wrapper for the perl "write" function is called "format_write".	[reply] [d/l]

Ah yes. Then it should probably return the bytes written. Unfortunately, it doesn't have that information available, and it wouldn't be feasible to do that.	[reply]

That's right, I misread the docs thinking it's mirroring C's `write()` function... oh well, thanks!	[reply] [d/l]

hum, Eliya pointed out that I was wrong and that IO::Handle's `write` does mirror C's (really POSIX's) `write`. Except in return value, of course. "This write is like write found in C"	[reply] [d/l] [select]
