PURPOSE

Fconcat, Fconcat32 - concatenate source to destination buffer

SYNOPSIS

#include <stdio.h>
#include "fml.h"
int
Fconcat(FBFR *dest, FBFR *src)
#include "fml32.h"
int
Fconcat32(FBFR32 *dest, FBFR32 *src)

DESCRIPTION

Fconcat() adds fields from the source buffer to the fields that already exist in the destination buffer. dest and src are pointers to the destination and source fielded buffers, respectively. Occurrences in the destination buffer, if any, are maintained and new occurrences from the source buffer are added with greater occurrence numbers for the field.

Fconcat32 is used with 32-bit FML.

RETURN VALUES

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

ERRORS

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

[FALIGNERR]

"fielded buffer not aligned"
Either the source buffer or the destination buffer does not begin on the proper boundary.

 

[FNOTFLD]

"buffer not fielded"
Either the source or the destination buffer is not a fielded buffer or has not been initialized by Finit().

 

[FNOSPACE]

"no space in fielded buffer"
A field value is to be added in a fielded buffer but there is not enough space remaining in the buffer.
