Windows GDI
EnumForms
The EnumForms function enumerates the forms supported by the specified printer.
BOOL EnumForms(
HANDLE hPrinter, // handle to printer object
DWORD Level, // data level
LPBYTE pForm, // form information buffer
DWORD cbBuf, // size of form information buffer
LPDWORD pcbNeeded, // bytes received or required
LPDWORD pcReturned // number of forms received
);
Parameters
- hPrinter
- [in] Handle to the printer for which the forms should be enumerated. Use the OpenPrinter or AddPrinter function to retrieve a printer handle.
- Level
- [in] Specifies the version of the structure to which pForm points. This value must be 1 or 2.
- pForm
- [out] Pointer to one or more FORM_INFO_1 structures or to one or more FORM_INFO_2 structures. All the structures will have the same level.
- cbBuf
- [in] Specifies the size, in bytes, of the buffer to which pForm points.
- pcbNeeded
- [out] Pointer to a variable that receives the number of bytes copied to the array to which pForm points (if the operation succeeds) or the number of bytes required (if it fails because cbBuf is too small).
- pcReturned
- [out] Pointer to a variable that receives the number of structures copied into the array to which pForm points.
Return Values
If the function succeeds, the return value is a nonzero value.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
If the caller is remote, and the Level is 2, the StringType value of the returned FORM_INFO_2 structures will always be STRING_LANGPAIR.
