The
sysdecode_fcntl_arg()
function outputs a text description of the optional
arg
argument to
fcntl(2)
to the stream
fp.
The type and format of
arg
are determined by
cmd:
| Command | arg, Sy, Type, Ta, Sy, Output, Format |
|
| F_SETFD | int | "FD_CLOEXEC"
or the value of
arg
in the indicated
base
(one of 8, 10, or 16).
|
|
| F_SETFL | int | File flags as output by
sysdecode_fcntl_fileflags(3)
with any unknown or remaining bits output in hexadecimal.
|
|
| F_GETLK | struct flock * | |
| F_SETLK | struct flock * | |
| F_SETLKW | struct flock * | The value of
arg
using the
"%p"
conversion specification.
|
|
Others | int | The value of
arg
in the indicated
base
(one of 8, 10, or 16).
|
The
sysdecode_fcntl_arg_p()
function can be used to determine if a
fcntl(2)
command uses the optional third argument to
fcntl(2).
The function returns
true
if
cmd
accepts a third argument to
fcntl(2)
and
false
if it does not.
