  Hi All,

  I am facing an issue related to _s string functions. Consider the following example.

  char szSrc[5] = {"Test"};

  char szDest [100] = {0};

   

  strcpy_s(szDest, sizeof(szDest) - 1, szSrc);

  This function copies the string "Test" to szDest along with NULL and 94 chars which follow Test<NULL> .

  In a prgrammer  perspective, this seems to be doing a memcpy for sizeof(szDest) - 1 bytes.

  Any comments?
