Overview
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 Type | Output Format |
| F_SETFD | int | |
| F_SETFL | int | |
| F_GETLK | struct flock * | |
| F_SETLK | struct flock * | |
| F_SETLKW | struct flock * | |
| Others | int |
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.
Return values
The sysdecode_fcntl_arg_p function returns true if cmd accepts a third argument to fcntl(2) and false if it does not.
