Yes, assuming you know how much you need before the loop starts. If not, you have no choice but to do it in the loop itself.
An alternative is to figure out a worst-case scenario (e.g., 2000 * sizeof(DWORD)) and allocate for that. While it will likely be too much most of the time, that's a whole lot cheaper (from the Memory Manager) than a ton of smaller requests.

if i allocate memory first of loop, for example with 256 bytes in size.
then i use 128 bytes of this size, in the loop.
when i free memory end of loop, is freed memory all of the 256 bytes? or the 128 bytes?
nonce, i test "allocate & free" in the loop itself.
then i inform you the result.
thank you

Hi all,
I have the following structure and piece of code:
typedef struct
#ifdef SAPonOS400
RFC_ERROR_INFO_EX
#endif
{
RFC_ERROR_GROUP group;
RFC_CHAR key[33];
RFC_CHAR message[513];
}
RFC_ERROR_INFO_EX;
RFC_ERROR_INFO_EX * error_info;
RfcLastErrorEx(error_info);
But then I receive this error:
Run-Time Check Failure #3 - The variable 'error_info' is being used without
being defined.
I know what it means but, don't know how to fix it, please help.
Many thanx

Modify this to,
RFC_ERROR_INFO_EX error_info;
RfcLastErrorEx(&error_info);

It happens to me lot of times , while posting replies. So, usually, I do refresh forum page in separate browser window, before finally posting it. Its very likely, while you type your post, somebody post same/simlar answer.

i am not able to use ::CommandLineToArgvW in EVC while the samething worked in VC . I have included the necessary shellapi.h and shell32.lib ,but am still getting errors like ,
error C2039: 'CommandLineToArgvW' : is not a member of '`global namespace''
error C2065: 'CommandLineToArgvW' : undeclared identifier
error C2440: 'initializing' : cannot convert from 'int' to 'unsigned short ** '

remove the prepended :: then
|
|
|
|

i tried removing :: too but only the globalnamespace error would be solved .
