   BEA Tuxedo FML Function Reference

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

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

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.

A thread in a multithreaded application may issue a call to Fused() or Fused32() while running in any context state, including TPINVALIDCONTEXT.

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

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().
