NAME

       sys_flock -  flock() system call.

SYNOPSIS

       asmlinkage long sys_flock (unsigned int fd, unsigned int cmd);

ARGUMENTS

       fd           the file descriptor to lock.

       cmd          the type of lock to apply.

DESCRIPTION

       Apply a FL_FLOCK style lock to an open file descriptor.  The cmd can be
       one of

       LOCK_SH -- a shared lock.

       LOCK_EX -- an exclusive lock.

       LOCK_UN -- remove an existing lock.

       LOCK_MAND -- a ‘mandatory’ flock.  This exists to emulate Windows Share
       Modes.

       LOCK_MAND  can  be combined with LOCK_READ or LOCK_WRITE to allow other
       processes read and write access respectively.
