C++ (Cpp) Str_Strchr Examples

Example #1

VixError
VixToolsValidateEnviron(char const * const *environ)   // IN
{
   if (NULL == environ) {
      return VIX_E_FAIL;
   }

   while (NULL != *environ) {

       * Each string should contain at least one '=', to delineate between
       * the name and the value.
       */

         return VIX_E_INVALID_ARG;
      }
