EnumPrintProcessors info Overview Group

The EnumPrintProcessors function enumerates the print processors installed on the specified server.

BOOL EnumPrintProcessors(

LPTSTR pName,	// points to server name
LPTSTR pEnvironment,	// points to environment name
DWORD Level,	// structure level
LPBYTE pPrintProcessorInfo,	// points to structure array
DWORD cbBuf,	// array length in bytes
LPDWORD pcbNeeded,	// points to number of bytes copied (or required)
LPDWORD pcReturned	// points to number of job info. structures copied
);

Parameters

pName: Points to a null-terminated string that specifies the name of the server on which the print processors reside. If this parameter is NULL, the local print processors are enumerated.
pEnvironment: Points to a null-terminated string that specifies the environment. For example, “Windows NT x86” specifies Windows NT running on an Intel 80386 or 80486 processor. If this parameter is NULL, the current environment of the calling application and client machine (not of the destination application and print server) is used.
Level: Specifies the version of the structure to which pPrintProcessorInfo points. This value must be 1.
pPrintProcessorInfo: Points to an array of PRINTPROCESSOR_INFO_1 structures. One structure is created for each available print processor.
cbBuf: Specifies the size, in bytes, of the buffer pointed to by pPrintProcessorInfo.
pcbNeeded: Points to a value that specifies the number of bytes copied if the function succeeds or the number of bytes required if cbBuf is too small.
pcReturned: Points to a value that specifies the number of PRINTPROCESSOR_INFO_1 structures that returned in the array to which pPrintProcessorInfo points.

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.
