Windows 10 inline functions of crt and strsafe

[TouEnMasm]

Here the vc++ project source code to create a lib with those inline functions (win 10 vc++ 2015)
Report are welcome

[jj2007]

A 300k C source for functions that most of us can hack together in ten minutes?

WSDK strsafe.lib is 30kb, so that wrapper is a bit larger :P
StrSafe.lib functions:

This lib is for WINDOWS 10 who put many functions INLINE
NO,you couldn't hack them in ten minutes .They are in c++ code in the include file,a bit too much hard for an asm compiler.

The lib is 300k with CRT and STRSAFE functions (471 public symbols).

By my experiance possible skip using all strsave functionality using SEH and a little more. Also _l functions of this lib have same prototypes as [n] functions, as strncpy and strcpy_l. So using them looks as bed style of programming.

in assembly language, the "safe" functions aren't really needed
we can design the code so that no buffer overflow is possible   :t

Your wording is a bit ambiguous, it could mean "don't use strsafe functions which rely on SEH" or "don't use strsafe functions, use SEH and unsafe functions instead". Both versions are dangerous. Relying on SEH is almost always a bad idea. For example, using a buffer overflow to write a new address into the stack will not trigger an exception.

Relying on SEH - strsave functionality, of throws when NULL pointers - used by _s functions of this lib, and better on SEH, as no need to care of all other types of functions, even you own. So both versions is correct - no ambiguous, and overflow preserves _l functions, that have same prototypes as [n] functions, as was said before - better to use them.
