DrawEscape function

Applies to: desktop apps only

The DrawEscape function provides drawing capabilities of the specified video display that are not directly available through the graphics device interface (GDI).

Syntax

Copy

int DrawEscape(
  __in  HDC hdc,
  __in  int nEscape,
  __in  int cbInput,
  __in  LPCSTR lpszInData
);

Parameters

hdc [in]: A handle to the DC for the specified video display.
nEscape [in]: The escape function to be performed.
cbInput [in]: The number of bytes of data pointed to by the lpszInData parameter.
lpszInData [in]: A pointer to the input structure required for the specified escape.

Return value

If the function is successful, the return value is greater than zero except for the QUERYESCSUPPORT draw escape, which checks for implementation only.

If the escape is not implemented, the return value is zero.

If an error occurred, the return value is less than zero.

Remarks

When an application calls the DrawEscape function, the data identified by cbInput and lpszInData is passed directly to the specified display driver.
