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.

The sysdecode_fcntl_arg_p function returns true if cmd accepts a third argument to fcntl(2) and false if it does not.
