GetTempPath
The GetTempPath
function retrieves the path of the directory designated for temporary files.
This function supersedes the GetTempDrive function.
DWORD GetTempPath(
|
DWORD nBufferLength, |
// size, in
characters, of the buffer |
|
LPTSTR lpBuffer |
// address of
buffer for temp. path |
|
); |
|
Parameters
nBufferLength
Specifies the
size, in characters, of the string buffer identified by lpBuffer.
lpBuffer
Points to a
string buffer that receives the null-terminated string specifying the temporary
file path.
Return Values
If the
function succeeds, the return value is the length, in characters, of the string
copied to lpBuffer, not including the terminating null character. If the
return value is greater than nBufferLength, the return value is the size
of the buffer required to hold the path.
If the
function fails, the return value is zero. To get extended error information, call
GetLastError.
Remarks
The GetTempPath
function gets the temporary file path as follows:
1. The path specified by the TMP environment variable.
2. The path specified by the TEMP environment variable, if TMP is not
defined.
3. The current directory, if both TMP and TEMP are not defined.
