Data type representing the QWF service context
#include <qwf/qwf_interface.h>
typedef struct qwf_Context_s qwf_Context_t;
The qwf_Context_t structure is an opaque data type that stores service context data needed by the API. The context is created and its structure is returned to a client program when it calls qwf_Init(). When it's finished using the API, the program must call qwf_Cleanup() to delete the data.
