NAME

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

See the file man1/alc_origin.1.

SYNOPSIS

#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)                                \
