   BEA Tuxedo FML Function Reference

Fsizeof, Fsizeof32(3fml)


Fsizeof(), Fsizeof32() - return size of fielded buffer


#include <stdio.h> 
#include "fml.h"

Fsizeof(FBFR *fbfr)

#include "fml32.h"

Fsizeof32(FBFR32 *fbfr)


Fsizeof() returns the size of a fielded buffer in bytes. fbfr is a pointer to a fielded buffer.

Fsizeof32() is used with 32-bit FML.

A thread in a multithreaded application may issue a call to Fsizeof() or Fsizeof32() while running in any context state, including TPINVALIDCONTEXT.

Return Values

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


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


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


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