The OEMDMPARAM structure is used as an input parameter to the IPrintOemUI::DevMode, IPrintOemUni::DevMode, and IPrintOemPS::DevMode methods.

Syntax

typedef struct _OEMDMPARAM {
  DWORD    cbSize;
  PVOID    pdriverobj;
  HANDLE   hPrinter;
  HANDLE   hModule;
  PDEVMODE pPublicDMIn;
  PDEVMODE pPublicDMOut;
  PVOID    pOEMDMIn;
  PVOID    pOEMDMOut;
  DWORD    cbBufSize;
} OEMDMPARAM, *POEMDMPARAM;

Members

cbSize

Contains the size of the OEMDMPARAM structure. Supplied by the Unidrv or Pscript5 driver.

pdriverobj

For IPrintOemUI::DevMode

Not used.

For IPrintOemUni::DevMode and IPrintOemPS::DevMode

Pointer to a DEVOBJ structure.

hPrinter

Handle to the printer device. Supplied by the Unidrv or Pscript5 driver.

hModule

Handle to the user interface plug-in module. Supplied by the Unidrv or Pscript5 driver.

pPublicDMIn

Pointer to the printer device's public DEVMODEW structure. Supplied by the Unidrv or Pscript5 driver. (Valid if the DevMode method's dwMode value is OEMDM_DEFAULT, OEMDM_CONVERT, or OEMDM_MERGE.)

pPublicDMOut

Pointer to a location to receive public DEVMODEW structure contents. Supplied by the Unidrv or Pscript5 driver. (Valid if the DevMode method's dwMode value is OEMDM_CONVERT or OEMDM_MERGE.)

pOEMDMIn

Pointer to a set of private DEVMODEW members. Supplied by the Unidrv or Pscript5 driver. (Valid if the DevMode method's dwMode value is OEMDM_CONVERT or OEMDM_MERGE.)

pOEMDMOut

Pointer to memory allocated to receive modified private DEVMODEW contents. Supplied by the Unidrv or Pscript5 driver. (Valid if the DevMode method's dwMode value is OEMDM_DEFAULT, OEMDM_CONVERT or OEMDM_MERGE.)

cbBufSize

On input, contains the caller-supplied size of memory space pointed to by pOEMDMOut. (Not valid if the DevMode method's dwMode value is OEMDM_SIZE.)

On output, contains the method-supplied size of the current version of the private DEVMODEW section. (Only used if the DevMode method's dwMode value is OEMDM_SIZE.)
