EnumPrintProcessorDatatypes info Overview Group

The EnumPrintProcessorDatatypes function enumerates the data types that a specifed print processor supports.

BOOL EnumPrintProcessorDatatypes(

LPTSTR pName,	// points to server name string
LPTSTR pPrintProcessorName,	// points to print processor name string
DWORD Level,	// specifies version of print processor data type structures
LPBYTE pDatatypes,	// points to buffer to receive print processor data type structures
DWORD cbBuf,	// specifies size, in bytes, of buffer
LPDWORD pcbNeeded,	// points to number of bytes copied (or required)
LPDWORD pcReturned	// points to number of data structures obtained
);

Parameters

pName: Points to a null-terminated string that specifies the name of the server on which the print processor resides. If this parameter is NULL, the data types for the local print processor are enumerated.
pPrintProcessorName: Points to a null-terminated string that specifies the name of the print processor whose data types are to be enumerated.
Level: Specifies the version of the print-processor data type structures to be stored in the buffer pointed to by pDatatypes. This parameter must be 1.
pDatatypes: Points to an array of DATATYPES_INFO_1 structures. One structure is created for each available data type.
cbBuf: Specifies the size, in bytes, of the buffer pointed to by pDatatypes.
pcbNeeded: Points to a variable to receive the total size, in bytes, of the array of DATATYPES_INFO_1 structures.
If this value is less than or equal to cbBuf and the function succeeds, this is the number of bytes stored in the buffer pointed to by pDatatypes. If this number is greater than cbBuf, the buffer is too small, and you must call the function again with a buffer size at least as large as *pcbNeeded.
pcReturned: Points to a variable that the function sets to the number of data structures stored in the buffer pointed to by pDatatypes.

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.
