NAME
fcntl - file control
SYNOPSIS
#include <fcntl.h>
int fcntl(int fildes, int cmd, ...);
DESCRIPTION
fcntl provides for control over open files. fildes is a file
descriptor obtained from a creat, dup, fcntl, open or pipe
call.
Since the fcntl call is nothing but an interface to the Fcntl
system call, the user is referred to the Fcntl page for an
overview of available commands.
SEE ALSO
creat(3),
dup(3),
fcntl(3),
open(3),
pipe(3)
RETURN VALUES
See Fcntl for a detailed description of return codes.
In general, -1 is returned on failure; any other value
indicates success; the meaning is dependent on the command
executed.
NOTES
Under TOS, fcntl always returns -1.
The available commands for Fcntl tend to increase all the
time; the current list is likely to be out of date.
