C++ (Cpp) DWRSEEK Examples

Example #1

File: virtstub.c Project: Graham-stott/open-watcom-v2

extern dr_handle DWRVMAlloc( unsigned long len, int sect )
/********************************************************/
{
    alloc_struct *nChunk;

    if( len == 0 ) {
        return( 0 );
    }

    nChunk = (alloc_struct *)DWRALLOC( len - 1 + sizeof( alloc_struct ) );
    if( nChunk == NULL ) {
        DWREXCEPT( DREXCEP_OUT_OF_MMEM );
        return( 0 );
    }

    nChunk->next = AllocHead;
    AllocHead = nChunk;

    DWRSEEK( DWRCurrNode->file, sect, 0 );
    DWRREAD( DWRCurrNode->file, sect, nChunk->data, len );

    return( (dr_handle)nChunk->data );
}

Example #2

File: virtmem.c Project: Azarien/open-watcom-v2

static void ReadPage( page_entry * node, virt_struct vm )
/*******************************************************/
/* read a page in from the dwarf file */
{
    unsigned long size;
    drmem_hdl     base;
    unsigned long offset;
    dr_section    sect;

    sect = node->sect;
    size = DWRCurrNode->sections[sect].size;
    base = DWRCurrNode->sections[sect].base;
    offset = (vm.l - base) & ~((unsigned long)OFFSET_MASK);
    size -= offset;
    if( size > MAX_NODE_SIZE ) {
        size = MAX_NODE_SIZE;
    }
    node->mem = DWRALLOC( size );
    node->inmem = true;
    ++PageCount;
    DWRSEEK( DWRCurrNode->file, sect, offset );
    DWRREAD( DWRCurrNode->file, sect, node->mem, size );
