Correction: "int syscall(int fd, int mode, ...)",

Here, we have syscall() with first argument being the system call number
- so what you suggested is not correct.

But, yes, the synopsis should change at some time. Maybe to something
like:

	#include <fcntl.h>

	long fallocate(int fd, int mode, loff_t offset, loff_t len);

There is not enough space left on the device containing the file
referred to by
.IR fd.
.TP
.B ESPIPE
.I fd
refers to a pipe of file descriptor.
.B ENOSYS
The filesystem underlying the file descriptor does not support this
operation.

EINTR?

Will add following errors:

  EINTR		A signal was caught during execution
  EIO		An I/O error occurred while reading from or writing to
		a file system.
  EOPNOTSUPP	The mode is not supported on the file descriptor.

and will update following :

  EINVAL	offset was less than 0, or len was less than or equal to 0.
