This pice of reply is from a 2002 question in NKS forum.

I'm currently seeing the same behavior for NSS volumes.

That is, NXDirEnumGetEntries return a 51 code (by the looks of it,
buffer to small).

Code:
#include <stdio.h>
#include <screen.h>
#include <string.h>
#include <dirio.h>

union
{
	NXDirAttr_t deDirAttr;
	NXDirMark_t deDirMark;
void *deName;
} buffer;

NXHandle_t              desHand;
size_t                  entriesReturned;
NXDirMark_t             next;
NXPathCtx_t             pCtx;
int						rc;
NXBool_t				sequenceGuarantee;

int main
(
	int	argc,
	char	*argv[],
	char	*env[]
)
{
#pragma unused (argc)
#pragma unused (env)

    if (argv[1] == NULL)
    {
        printf("FileIO rootpath\n");
        goto Exit;
    }
    printf("Root path (%s)\n", argv[1]);

    rc = NXCreatePathContext(0, argv[1], NX_PNF_NKS, 0, &pCtx);
    printf("NXCreatePathContext rc(%x)\n", rc);
    if (rc) goto Exit;
        
    rc = NXDirEnumStart(pCtx, ".", NX_DELEVEL_BASIC, &desHand);
    printf("NXDirEnumStart(pCtx rc(%x)\n", rc);
    if (rc) goto ExitPCtx;
           
    rc = NXDirMarkInit(desHand /*pCtx*/, &next);
    printf("NXDirMarkInit rc(%x)/n", rc);
    printf("rc = %x\n", rc);
    if (rc) goto ExitPCtx;    
    

    rc = NXDirEnumGetEntries(desHand, &next, &buffer, sizeof(buffer),

	return 0;
