示例1:
/* Destroy a pixmap*/
void
GsDestroyPixmap(GR_PIXMAP *pp)
{
GR_PIXMAP *prevpp;
PSD psd = pp->psd;
/* deallocate mem gc*/
psd->FreeMemGC(psd);
/*
* Remove this pixmap from the complete list of pixmaps.
*/
prevpp = listpp;
if (prevpp == pp)
listpp = pp->next;
else {
while (prevpp->next != pp)
prevpp = prevpp->next;
prevpp->next = pp->next;
}
/*
* Forget various information if they related to this
* pixmap. Then finally free the structure.
*/
if (pp == cachepp) {
cachepixmapid = 0;
cachepp = NULL;
}
free(pp);
}示例2: GetDCEx
/* return NULL if no driver bitblit available*/
HDC WINAPI
CreateCompatibleDC(HDC hdc)
{
HDC hdcmem;
PSD psd;
PSD mempsd;
/* allow NULL hdc to mean screen*/
psd = hdc? hdc->psd: &scrdev;
/* allocate memory device, if driver doesn't blit will fail*/
mempsd = psd->AllocateMemGC(psd);
if(!mempsd)
return NULL;
/* allocate a DC for DesktopWindow*/
hdcmem = GetDCEx(NULL, NULL, DCX_DEFAULTCLIP);
if(!hdcmem) {
mempsd->FreeMemGC(mempsd);
return NULL;
}
hdcmem->psd = mempsd;
/* select in default bitmap to setup mem device parms*/
SelectObject(hdcmem, (HGDIOBJ)&default_bitmap);
return hdcmem;
}
