Function name : EnumPrinterDrivers

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

Enumerates the printer drivers installed on a specified printer server.

Code examples:

Enumerating printer drivers installed

Declaration:

BOOL EnumPrinterDrivers(
  LPTSTR pName,        // printer server name
  LPTSTR pEnvironment, // environment name
  DWORD Level,         // information level
  LPBYTE pDriverInfo,  // driver information buffer
  DWORD cbBuf,         // size of driver information buffer
  LPDWORD pcbNeeded,   // bytes received or required
  LPDWORD pcReturned   // number of drivers received
);

FoxPro declaration:

DECLARE INTEGER EnumPrinterDrivers IN winspool.drv;
	STRING    pName,;
	STRING    pEnvironment,;
	INTEGER   Level,;
	STRING  @ pDriverInfo,;
	INTEGER   cdBuf,;
	INTEGER @ pcbNeeded,;
	INTEGER @ pcReturned

Parameters:

pName [in] Pointer to a null-terminated string that specifies the name of the server on which the printer drivers are enumerated.

pEnvironment [in] Pointer to a null-terminated string that specifies the environment

Level [in] Specifies the type of information structure returned in the pDriverInfo buffer.

pDriverInfo [in] Pointer to a buffer that receives an array of DRIVER_INFO_* structures, as specified by Level.

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

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

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

Return value:

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

Comments:

Not like some other enumerating functions this one does not need a call-back procedure. It returns data in an array.
