Close a context.
#include <mm/renderer.h>
int mmr_context_close( mmr_context_t *ctxt )
Close and invalidate the context handle. The handle passed to mmr_context_close() always gets closed and becomes invalid, even if the function returns an error. Depending on the configuration, the context the handle refers to might also be destroyed. In this case, mmr_context_close() returns -1 and also sets the global variable errno to EPERM. For more information about context handles, see "Working with contexts".
Zero on success, -1 on failure (check errno). The handle becomes invalid either way.
