PURPOSE

Fused, Fused32 - return number of used bytes in fielded buffer

SYNOPSIS

#include <stdio.h>
#include "fml.h"
long
Fused(FBFR *fbfr)
#include "fml32.h"
long
Fused32(FBFR32 *fbfr)

DESCRIPTION

Fused() returns the amount of used space in a fielded buffer in bytes, including both user data and the header (but not the index, which can be dropped at any time). fbfr is a pointer to a fielded buffer.

Fused32 is used with 32-bit FML.

RETURN VALUES

This function returns -1 on error and sets Ferror to indicate the error condition.

ERRORS

Under the following conditions, Fused() fails and sets Ferror to:

[FALIGNERR]

"fielded buffer not aligned"
The buffer does not begin on the proper boundary.

 

[FNOTFLD]

"buffer not fielded"
The buffer is not a fielded buffer or has not been initialized by Finit().
