This code demonstrates how to get the space actually allocated by the data stream of a given file with NWGetNSEntryInfo()

Sample Code

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#ifdef __MWERKS__
#pragma ANSI_strict off
#endif
#include <nwcalls.h>
#include <nwclxcon.h>
#include <nwnamspc.h>
#ifdef __MWERKS__
#pragma ANSI_strict reset
#endif

#if defined( __MWERKS__) && !defined( N_PLAT_NLM)
#define strupr(s) (_strupr(s),s)
#endif

int main( int argc, char* argv[]) {
  char const*   server_name;
  char const*   file_name;
  NWRCODE       rcode;
  NWCCODE       ccode;
  NWCONN_HANDLE conn_handle;
  NW_ENTRY_INFO ns_entry_info;
  if ( argc != 3) {
    printf( "Usage: %s <servername> <filename>\n", *argv);
    return EXIT_FAILURE;
  }
  ccode = NWCallsInit( NULL, NULL);
  if ( ccode != 0) {
    printf( "NWCallsInit failed, ccode = %x", ccode);
    return EXIT_FAILURE;
  }
  server_name = strupr( *++argv);
  file_name   = strupr( *++argv);
  rcode = NWCCOpenConnByName( 0,
                              server_name,
                              NWCC_NAME_FORMAT_BIND,
                              NWCC_OPEN_LICENSED,
                              NWCC_TRAN_TYPE_WILD,
                              &conn_handle);
  if ( rcode != 0) {
    printf( "NWCCOpenConnByName failed, rcode = %x", rcode);
    NWCallsTerm( NULL);
    return EXIT_FAILURE;
  }
  ccode = NWGetNSEntryInfo( conn_handle, 0, file_name, NW_NS_LONG, NW_NS_LONG, SA_NORMAL, IM_SPACE_ALLOCATED, &ns_entry_info);
  if ( ccode != 0) {
    printf( "NWGetNSEntryInfo failed, ccode = %x", ccode);
    NWCCCloseConn( conn_handle);
    NWCallsTerm( NULL);
    return EXIT_FAILURE;
  }
  printf( "ns_entry_info.spaceAlloc = %d\n", ns_entry_info.spaceAlloc);
  NWCCCloseConn( conn_handle);
  NWCallsTerm( NULL);
  return EXIT_SUCCESS;
}
