PetscDrawCollectiveBegin#

Begins a set of draw operations Collective

Synopsis#

#include <petscdraw.h>
PetscErrorCode PetscDrawCollectiveBegin(PetscDraw draw)

Collective

This is a macro that handles its own error checking, it does not return an error code.

The set of operations needs to be ended by a call to PetscDrawCollectiveEnd().

X windows draw operations that are enclosed by these routines handle correctly resizing or closing of the window without crashing the program.

This only applies to X windows and so should have a more specific name such as PetscDrawXCollectiveBegin()
