SYNOPSIS

#include <stdio.h>
#include "fml.h"
FLDOCC
Foccur(FBFR *fbfr, FLDID fieldid)
#include "fml32.h"
FLDOCC32
Foccur32(FBFR32 *fbfr, FLDID32 fieldid)

DESCRIPTION

Foccur() is used to determine the number of occurrences of the field specified by fieldid in the buffer pointed to by fbfr.

Foccur32 is used with 32-bit FML.

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.

ERRORS

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

[FALIGNERR]

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

 

[FNOTFLD]

"buffer not fielded"
