[splint-discuss] how to satisfy splint on the " global variable" declaration.

[juan abba]

hi

I cant find the way to satisfy splint on the " global variable"  
declaration.

I declare a global on the MAIN file, out of any block.

on another " C" file, were same variable will be used, I  declare it 
using the " external" keyword before the declaration, but splint don't 
like it, as follows
=================================================================================
teste_anexo.c(17,18): Variable Daa declared more than once
  A function or variable is declared in more than one place. This is not
  necessarily a problem, since the declarations are consistent. (Use 
-redecl to
  inhibit warning)
   doubleXlong_main.c(87,8): Previous declaration of Daa
   ==============================================================
  
   if I declare it as extern  withing the function I get:
  
   ================================================
   teste_anexo.c(25,18): Variable Daa shadows outer declaration
  An outer declaration is shadowed by the local declaration. (Use -shadow to
  inhibit warning)
   doubleXlong_main.c(87,8): Previous definition of Daa: double
teste_anexo.c(25,22): Declaration using extern inside function scope:
                         double Daa
  An extern declaration is used inside a function scope. (Use 
-nestedextern to
  inhibit warning)
  ================================================================
  
   of course I can inhibit the warnings, but I wonder which is the way 
to use "external" correctly and 100% withing the SPLINT criteria??????

   thanks in advance
