EnumForms info Overview Group

The EnumForms function enumerates the forms supported by the specified printer.

BOOL EnumForms(

HANDLE hPrinter,	// handle to printer object
DWORD Level,	// data-structure level
LPBYTE pForm,	// points to buffer that receives form info. structure array
DWORD cbBuf,	// count of bytes in buffer
LPDWORD pcbNeeded,	// points to variable to receive count of bytes copied or required
LPDWORD pcReturned	// points to variable to receive count of structures copied
);

Parameters

hPrinter: Identifies the printer for which the forms should be enumerated.
Level: Specifies the version of the structure to which pForm points. This value must be 1.
pForm: Points to a FORM_INFO_1 structure.
cbBuf: Specifies the size, in bytes, of the buffer to which pForm points.
pcbNeeded: Points to a variable that receives the number of bytes copied to or the number of bytes required for the array to which pForm points. If cbBuf is too small, this value specifies the number of bytes required; otherwise, this value specifies the number of bytes copied.
pcReturned: Points to a variable that receives the number of FORM_INFO_1 structures copied into the array to which pForm 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.

The printer-object handle hPrinter is normally obtained by calling the OpenPrinter function. The AddPrinter function can also be used.
