Yes, this is very, very wrong.

Look into this:


GetTempPath
The GetTempPath function retrieves the path of the directory designated for 
temporary files. 

DWORD GetTempPath(
  DWORD nBufferLength,  // size, in characters, of the buffer
  LPTSTR lpBuffer       // pointer to buffer for temp. path
);
     
Parameters
     nBufferLength 
     Specifies the size, in characters, of the string buffer identified by 
lpBuffer. 
     lpBuffer 
     Pointer to a string buffer that receives the null-terminated string 
specifying the temporary file path. The returned string ends with a backslash, 
for example, C:\TEMP\. 

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.
