Just an FYI... Anyone working with C/C++ should be well aware of the functions we should be avoiding: http://hub.opensolaris.org/bin/view/Community+Group+security/funclist
Microsoft has used the term "banned" and has a much more extensive list: http://msdn.microsoft.com/en-us/library/bb288454.aspx Unfortunately, we often cannot use the recommended replacements unless we know that the replacement is available on all platforms, however, some are fairly obvious, like using snprintf instead of sprintf. Functions like sprintf, vsprintf, strcat, strcpy, access, chmod, chown, lchown, chdir, ... all have know issues or have caused too many common mistakes over the years, we need to avoid the use of these functions. -kto
