Exemple #1

{

    uint_8      *buf;
    bool        ok;

    size = 0;
    buf = NULL;

    ok = (src_fid != WRES_NIL_HANDLE && dst_fid != WRES_NIL_HANDLE);

    ok = (ok && (buf = (uint_8 *)MemAlloc( CHUNK_SIZE )) != NULL);

    ok = (ok && RESSEEK( src_fid, offset, SEEK_SET ) != -1);

    while( ok && length - size > CHUNK_SIZE ) {
