BOOTSTRAP (kutils) functions


LIBRARY ROUTINE

kwrite - write output to a transport descriptor

LIBRARY CALL

ssize_t kwrite(
   int   id,
   kaddr buf,
   size_t   nbytes)

INPUT

OUTPUT

none

RETURN VALUE

The number of bytes written, or -1 when an error is encountered.

DESCRIPTION

This function is a replacement for the system "write" call. The only difference is that kwrite() supports more than just files, it supports other data transports as well, such as shared memory, pipes, files, etc.

The routine will write nbytes from the character array "buf" to the appropriate transport mechanism specified by id. If not all nbytes can be read then the kread() routine returns the number of bytes actually read.
