NAME¶

XcvDataW (WINSPOOL.@)

SYNOPSIS¶

BOOL XcvDataW
(
HANDLE hXcv,
LPCWSTR pszDataName,
PBYTE pInputData,
DWORD cbInputData,
PBYTE pOutputData,
DWORD cbOutputData,
PDWORD pcbOutputNeeded,
PDWORD pdwStatus
)

DESCRIPTION¶

Execute commands in the Printmonitor DLL.

PARAMS¶

hXcv [In] Handle from OpenPrinter (with XcvMonitor or XcvPort). pszDataName [In] Name of the command to execute. pInputData [In] Buffer for extra Input Data (needed only for some commands). cbInputData [In] Size in Bytes of Buffer at pInputData. pOutputData [Out] Buffer to receive additional Data (needed only for some commands). cbOutputData [In] Size in Bytes of Buffer at pOutputData. pcbOutputNeeded [Out] PTR to receive the minimal Size in Bytes of the Buffer at pOutputData. pdwStatus [Out] PTR to receive the Win32 error code from the Printmonitor DLL.

RETURNS¶

Success: TRUE Failure: FALSE.

NOTES¶

Returning "TRUE" does mean, that the Printmonitor dll was called successful. The execution of the command can still fail (check pdwStatus for ERROR_SUCCESS). Minimal List of commands, that a Printmonitor dll should support:
"MonitorUI" : Return the Name of the Userinterface-DLL as WSTR in pOutputData
"AddPort" : Add a Port
"DeletePort": Delete a Port. Many Printmonitors support additional commands. Examples for localspl.dll: "GetDefaultCommConfig", "SetDefaultCommConfig", "GetTransmissionRetryTimeout", "ConfigureLPTPortCommandOK"

IMPLEMENTATION¶

Declared in "winspool.h". Implemented in "dlls/winspool.drv/info.c". Debug channel "winspool".
