   BEA Tuxedo FML Function Reference

Foccur, Foccur32(3fml)


Foccur(), Foccur32() - return count of field occurrences in buffer


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

Foccur(FBFR *fbfr, FLDID fieldid)

#include "fml32.h"

FLDOCC32 Foccur32(FBFR32 *fbfr, FLDID32 fieldid)


Foccur() is used to determine the number of occurrences of the field specified by fieldid in the buffer referenced by fbfr. Occurrences of a field within an embedded FML32 buffer are not counted, as in the FLD_FML32 field type.

Foccur32() is used with 32-bit FML.

A thread in a multithreaded application may issue a call to Foccur() or Foccur32() while running in any context state, including TPINVALIDCONTEXT.

Return Values

On success, Foccur() returns the number of occurrences; if none are found, it returns 0.

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


Under the following conditions, Foccur() 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().


"unknown field number or type"
A field identifier is specified which is not valid.
