#include "rwinnn.h"
 rdsrecwin_list ∗allocrdsrecwin()

none

The allocrdsrecwin function allocates a rdsrecwin_list structure item. This structure contains a pointer to a window structure so it permits to chain all windows which contains a same rectangle (see librwi).

The pointer to the newly allocated structure is returned.
