Function name : EnumPrintProcessorDatatypes

Group: Printing and Print Spooler - Library: winspool.drv

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

Code examples:

Enumerating print processors and supporting data types installed on the specified server

Declaration:

BOOL EnumPrintProcessorDatatypes(
  LPTSTR pName,                // printer server name
  LPTSTR pPrintProcessorName,  // print processor name
  DWORD Level,                 // information level
  LPBYTE pDatatypes,           // processor data buffer
  DWORD cbBuf,                 // size of data buffer
  LPDWORD pcbNeeded,           // bytes received or required
  LPDWORD pcReturned           // number of processors
);

FoxPro declaration:

DECLARE INTEGER EnumPrintProcessorDatatypes IN winspool.drv;
	STRING    pName,;
	STRING    pPrnProcName,;
	INTEGER   Level,;
	STRING  @ pDatatypes,;
	INTEGER   cbBuf,;
	INTEGER @ pcbNeeded,;
	INTEGER @ pcReturned

Parameters:

pName [in] Pointer to a null-terminated string that specifies the name of the server on which the print processor resides.

pPrintProcessorName [in] Pointer to a null-terminated string that specifies the name of the print processor whose data types are enumerated.

Level [in] Specifies the type of information returned in the pDatatypes buffer. This parameter must be 1.

pDatatypes [out] Pointer to a buffer that receives an array of DATATYPES_INFO_1 structures.

cbBuf [in] Specifies the size, in bytes, of the buffer pointed to by pDatatypes.

pcbNeeded [out] Pointer to a variable that receives the number of bytes copied to the pDatatypes buffer if the function succeeds.

pcReturned [out] Pointer to a variable that receives the number of structures returned in the pDatatypes buffer.

Return value:

If the function succeeds, the return value is a nonzero value.
