Format
void MgraInquire(GraphContId, ParamToInquire, UserVarPtr)
| MIL_ID GraphContId; | Graphics context identifier |

| void *UserVarPtr; | Storage location for inquiry result |
Description
This function inquires about a graphic parameter in the specified graphics context.
The GraphContId parameter specifies the identifier of the graphics context on which to perform the inquiry. This parameter can be set to M_DEFAULT, in which case the default graphics context of the current MIL application is used.

| M_BACKGROUND_MODE | Background mode. |
| M_FONT | Character font. |
| M_FONT_X_SCALE | Font scaling factor in X. |
| M_FONT_Y_SCALE | Font scaling factor in Y. |
| M_OWNER_SYSTEM | MIL identifier (MIL_ID) of the system on which the graphics context has been allocated (MgraAlloc). |
The UserVarPtr parameter specifies the address of the variable in which the requested information is to be written.
This variable should be defined as follows:
| InquireType | Pointer to a: |
| M_COLOR | double * |
| M_BACKCOLOR | double * |
| M_BACKGROUND_MODE | long * |
| M_FONT | void * |
| M_FONT_X_SCALE | double * |
| M_FONT_Y_SCALE | double * |
| M_OWNER_SYSTEM | MIL_ID * |
