hye can anyone give me the example of memset function

[shabbir]

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

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

[Salem]

> memset(szPath,'\0',MAX_PATH);
And if TCHAR isn't a char, then you'll need one of

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.
