A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the eighth batch of tests being updated (there are a
significant number of other tests left to be updated).
When emitting a bug report, it is important to highlight which argument of the
call-expression is causing the problem.
Before:
warning: Null pointer argument in call to string comparison function
strcmp(a, b);
^~~~~~~~~~~~
After:
warning: Null pointer argument in call to string comparison function
strcmp(a, b);
^ ~
Affects other output modes as well, not just text.
