int r = hw_RaiseOnError(lua_State *L, int error, struct hwTagList *tags);

This function is only here for people who need fine-tuned control over Hollywood's automatic error handler. Normally it is not needed to call this function manually. Under normal circumstances, managing error handlers should be left to Hollywood. If you need fine-tuned control over the error handler, you may also want to take a look at the HWMCP_SETDISABLERAISEONERROR tag for hw_MasterControl(). See hw_MasterControl for details.

Note that certain error codes need additional information that you have to specify by calling either hw_SetErrorString() or hw_SetErrorCode(). See Error codes for details.

L

pointer to the lua_State

error

error code you want to throw

tags
