NAME

allocrdsrecwin - allocates a structure used to know windows which contains a rectangle.

See the file buster/alliance/alc_origin.1.en.gz.

SYNOPSYS

#include "rwinnn.h"


 rdsrecwin_list ∗allocrdsrecwin()

PARAMETER

none

DESCRIPTION

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).

RETURN VALUE

The pointer to the newly allocated structure is returned.

ERRORS

"Rds202: rdsalloc error, can't continue !"

it's impossible to allocate the memory size desired

EXAMPLE



        #include "mutnnn.h"


        #include "rdsnnn.h"


        #include "rwinnn.h"


        #include "rtlnnn.h"


        # define POINTER_WINDOW(R)                                \

          (((UserStruct ∗)((char ∗)(R)+sizeof(rdsrec_list)))->WINDOW )
