Subject: A question on cat.asm from asmutils-0.17
Date: Tue, 18 Nov 2003 11:56:29 +0800	[thread overview]
Message-ID: <3FB9986D.60709@cbf.chinese2000.net> (raw)

Hi All,

I'm trying to get acquintant with Linux assembly language by studying
the asm code found in asmutils.

While studying cat.asm, I discover that every time a file is opened
using sys_open, there is no correspondent sys_close to it. (The codes
were marked).

I would like to ask if this is an legitimate way to open a file without
closing it under Linux, or just a convenient way to let the
shell/kernel(I'm not sure...) to close the file for us when cat is
finished.  For my experience on MS-DOS assembly, I must close an
opened-file, or otherwise I'll encounter an out of file handle error.

Thanks and Regards,
Lawrence
