allocrdsrecwin(3)
allocates a structure used to know windows which contains a rectangle.
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

#include "mutnnn.h"
