Subject: [splint-discuss] Function interface annotations
Message-ID: <7A407C25F211BE428DF593363B385D93036373F2@si-mail02.de.bosch.com>

Hi,

I want to use annotations to specify the interface of a function. I want
to specify every variable that is an input to the function (except
variables passed by value; this is obvious by the parameter list) and
every variable that is output of that function (if not returned by
return()). Also, i want to specify the side-effects of the function. For
that purpose, I want to use @in@, @out@, @modifies@, @globals@
annotations.

Is this the correct approach?

I have some questions on these annotations:

/*@in@*/ int *p: Is p or *p mutable?

/*@out@*/ int *p: Does p have to be allocated? That is, if p==NULL, does
splint generate an error?
             Do I have to include *p in @modifies@?

@globals@: How do I specify that a function does not use any globals?

Regards,
Boris

Subject: [splint-discuss] C99 types
Message-ID: <7A407C25F211BE428DF593363B385D93036373F3@si-mail02.de.bosch.com>

Hi,

I have a problem with C99 types, such as uint8_t, int32_t. It seems that
Splint knows these types even if I don't include a header file that
contains definitions for these types (eg, types.h or stdint.h). However,
the compiler won't accepts C99 types without a corresponding header
file.

On the other hand, if I include the header file containing definitions
for these types, Splint complains about improper definitions. 

How do I resolve this problem?

Regards,
Boris

It sounds like it might help you to try -skipposixheaders.

 

If that doesn't work, you might get a better response if you include

example code that's giving you trouble.  This gave me no errors from 

splint or gcc (on cygwin), with no extra arguments to either:

 

#include <stdint.h>

 

int main(void) {

    uint32_t x = 72;

    return (int)x;

}
