{{DISPLAYTITLE:DEVESC_STD_JOURNAL}}
GreEscape DEVESC_STD_JOURNAL sends a standard journal file to the presentation driver. 

;Simulation support: This function is mandatory for hardcopy drivers, but may simply return a DEVESC_NOTIMPLEMENTED code. For other drivers, it is simulated by a handling routine in the graphics engine. 

==Syntax==
 GreEscape(hdc, lEscape, cInCount, pInData, pcOutCount, pOutData, pInstance, lFunction)

==Parameters==
;hdc (HDC) - input 
:Device context handle. 

;lEscape (LONG) - input 
:DEVESC_STD_JOURNAL escape code. 

;cInCount (LONG) - input 
:Number of bytes pointed to by pInData. 

;pInData (PBYTE) - input 
:Pointer to journal data. 

;pcOutCount (PLONG) - input 
:The handling routine ignores this parameter. 

;pOutData (PLONG) - input 
:The handling routine ignores this parameter. 

;pInstance (PVOID) - input 
:Pointer to instance data. 

;lFunction (ULONG) - input 
:High-order WORD=flags; low-order WORD=NGreEscape. 


==Returns==
;rc (LONG) - returns 
:Return Code. 
:The handling routine returns: 
:;DEV_OK 
::Successful 
:;DEVESC_NOTIMPLEMENTED 
::Escape not implemented for specified code 
:;DEVESC_ERROR 
::Error 

==Remarks==
Note: This escape is implemented by old hardcopy drivers and is being phased out.
