SWAPI_ContinentIDToContinentName
This function retrieves the continent name by the continent ID.
Syntax
| Microsoft Visual C++ |
DWORD __stdcall SWAPI_ContinentIDToContinentName(
UCHAR ContinentID,
PVOID DstBuff,
DWORD DstSize
); |
|
| Borland Delphi |
function SWAPI_ContinentIDToContinentName(
const ContinentID: Byte;
const DstBuff: Pointer;
const DstSize: DWORD
): DWORD; stdcall; |
|
| Microsoft Visual Basic |
Declare Function SWAPI_ContinentIDToContinentName Lib "swapimap.dll" (
ByVal ContinentID As Byte,
ByVal DstBuff As String,
ByVal DstSize As Long
) As Long |
|
Parameters
| ContinentID |
[in] Continent ID retrieved by using the functions for obtaining the continent ID.
|
| DstBuff |
[out] Pointer to the buffer to receive the string containing the continent name.
|
| DstSize |
| [in] Size of the buffer specified by the DstBuff parameter in bytes. This value should be set to 13 or greater. |
Return Value
If the function succeeds, the return value is non-zero. If the return value is greater than DstSize, the value returned is the size of DstBuff required to hold the name. Otherwise, the value returned is the length of the string copied to DstBuff.
If the function fails, the return value is zero.
Remarks
The terminating null character is not copied to the buffer specified by DstBuff. Use the function return value to determine the length of the string copied to DstBuff.
