i am seeing constructs like this at
several locations of the XFree86 sources:
*.h:
extern char *Xpermalloc(
#if NeedFunctionPrototypes
unsingend int /* size */
#endif
);
*.c:
char *Xpermalloc(unsigned int length)
{ ... }
#if NeedFunctionPrototypes
XrmQuark XrmStringToQuark(
_Xconst char *name)
#else
XrmQuark XrmStringToQuark(name)
XrmString name;
#endif
{ ... }
for my impression the applied macro check
is obsolete nowadays and should not used
any longer for current coding. the phrase
inside the first #if #endif is a needed one.
i think for the second one the if-case is
probably the prefered coding style whilst
the else-case is the obsolete coding style.
am i right? this is a pure leftover?
or am i wrong and some targets do still
have some heavy dependencys on that?
are there some coding guidlines somewhere
in the tree that do outline on that subject?
i am personally targetting on compatible
coding and avoiding breakage of other codes.
-Alex.
PS: i am hoping for a response of some long term
XFree86 developer to answer this.
