PmMemSetType()

Set the type of a memory context

Synopsis:

#include <photon/PhRender.h>

void PmMemSetType( PmMemoryContext_t *mc,
                   int type );

Library:

ph

Description:

This function sets the type of the memory context pointed to by mc. The valid types are:

Pm_PHS_CONTEXT

Renders the draw buffer to image only when necessary (i.e. when the draw buffer is full, or PmMemFlush() is explicitly called). Otherwise, the only effect a flush has is to expand the draw buffer when necessary.

Pm_IMAGE_CONTEXT

The draw stream is rendered to the image on every flush.

Classification:
