Retrieves the last error description or server response on the thread calling this function.
BOOLAPI InternetGetLastResponseInfoA( LPDWORD lpdwError, LPSTR lpszBuffer, LPDWORD lpdwBufferLength );
Pointer to a variable that receives an error message pertaining to the operation that failed.
Pointer to a buffer that receives the error text.
Pointer to a variable that contains the size of the lpszBuffer buffer, in TCHARs. When the function returns, this parameter contains the size of the string written to the buffer, not including the terminating zero.
Returns TRUE if error text was successfully written to the buffer, or FALSE otherwise. To get extended error information, call GetLastError. If the buffer is too small to hold all the error text, GetLastError returns ERROR_INSUFFICIENT_BUFFER, and the lpdwBufferLength parameter contains the minimum buffer size required to return all the error text.
The FTP protocols can return additional text information along with most errors. This extended error information can be retrieved by using the InternetGetLastResponseInfo function whenever GetLastError returns ERROR_INTERNET_EXTENDED_ERROR (occurring after an unsuccessful function call).
The buffer pointed to by lpszBuffer must be large enough to hold both the error string and a zero terminator at the end of the string. However, note that the value returned in lpdwBufferLength does not include the terminating zero.
InternetGetLastResponseInfo can be called multiple times until another function is called on this thread. When another function is called, the internal buffer that is storing the last response information is cleared.
Like all other aspects of the WinINet API, this function cannot be safely called from within DllMain or the constructors and destructors of global objects.
