Re: memset function

Code:

TCHAR szPath[MAX_PATH];

memset(szPath,'\0',MAX_PATH);

It will have all the memory location of szPath filled with '\0'

And if TCHAR isn't a char, then you'll need one of

Code:

memset(szPath,'\0',MAX_PATH * sizeof TCHAR );

memset(szPath,'\0',MAX_PATH * sizeof szPath[0] );

memset(szPath,'\0',sizeof szPath );

Focus on the bit about "all-bits-zero". In other words, don't rely on memset giving you valid floats or pointers, if you try the same approach on attempting to clear more complex data types.
