fdds_check - DDS, check memory heap

SYNOPSIS

#include <fdds.h> (fixed-format sources)
#include <f90dds.h> (free-format sources)

integer fdds_check(flags)

integer flags

DESCRIPTION

This function allows the application to control debug checking. The "flags" field is an integer and can be any of the DDS_DEBUG flags listed below. Successive invokation of fdds_check causes multiple debug flags to be OR'd together. The return value is the debug flag combination before fdds_check is invoked so that it can be used to restore the original state when needed. Similar functionality, though with less control, is available by using run-time parameter dds_debug= debug flags.

Flags

    DDS_DBG_HEAP      (check heap once, right now)
    DDS_DBG_ALLOC     (check heap on each allocation)
    DDS_DBG_FREE      (check heap on each free)
    DDS_DBG_CALL      (check heap on each DDS API call)
    DDS_DBG_TRACE     (trace all API calls)
    DDS_DBG_SCANNER   (trace compiler scanner)
    DDS_DBG_SYMBOL    (dump binary symbol tables)
    DDS_DBG_UNCOMPILE (dump ddsUncompileFmt stacks)
    DDS_DBG_BINARY    (dump binary ? tables)
    DDS_DBG_PANIC     (dump binary tables on panic)
