POSIX Programmerís Manual is available on Linux
Modern Linux distros provide POSIX Programmerís Manual in manpages, sections
0p
,
1p
, and
3p
. You can check if it works on your machine:
123
man 0p stdio.h
man 1p exit
man 3p open
You can consult the POSIX documentation while coding on a beach or in an airplane, without Internet connection. It is always on your fingertips.
Sections
0p
,
1p
, and
3p
are devoted to documentation about, respectively, header files, user commands (command line), and functions called from codes written in
C
language.
Note that commands and section are capitalized on POSIX manpages: subject
open
in section
3p
is documented as
OPEN(3P)
. Of course, it is wrong: commands
123
man 3P OPEN
man 3P open
man 3p OPEN
print diagnostics like
1
No entry for OPEN in section 3P of the manual
instead of expected manpages.
