int kjb_write_2
(
	int des,
	const void *buff,
	size_t len,
	size_t *len_ptr
);

PARAMETERS

int des: File descriptor
const void *buff: Pointer to bytes to write
size_t len: Number of bytes to write.
size_t *len_ptr: Number of bytes written.

DESCRIPTION

This routine is similar to write (but note the difference in arguments!). However, error handling is made more consistant with the rest of the KJB library. Several other KJB library IO conventions and features are also implemented. (One should not mix KJB and non-KJB IO)! The number of bytes that are written are returned in len_ptr. This can be set to NULL if you are not interested.

RETURNS

On success kjb_write returns the number of bytes written. On failure ERROR is returned and an error message is set.

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
