Name

Fpres(), Fpres32() - true if field occurrence is present in buffer

#include <stdio.h> 
 
#include "fml.h" 
 
int 
Fpres(FBFR *fbfr, FLDID fieldid, FLDOCC oc) 
 
#include "fml32.h" 
 
int 
Fpres32(FBFR32 *fbfr, FLDID32 fieldid, FLDOCC32 oc)

Description

Fpres() is used to detect whether a given occurrence (oc) of a specified field (fieldid) exists in the buffer referenced by fbfr. Fpres32() does not check for occurrences of the specified field within an embedded buffer, as in the FLD_FML32 field type.

Fpres32() is used with 32-bit FML.

A thread in a multithreaded application may issue a call to Fpres() or Fpres32() while running in any context state, including TPINVALIDCONTEXT.

Return Values

Fpres() returns true if the specified occurrence exists and false otherwise.
