Rule 11.9 : Global initialization of pointers - Akhil - 13-03-2015
In this case :
1. int *ptr ; // Is this compliant or non compliant
2. void foo()
3. {
4. /* Do Something. */
5. }
Global variables are initialized to 0 by default.
This means ptr is initialized to 0 automatically by compiler.
Ques : Is line 1 compliant or non compliant to Rule 11.9.
Does this rule also enforce initializing ptr to NULL for global pointers. ?
Re: Rule 11.9 : Global initialization of pointers - misra-c - 27-03-2015
Rule 11.9 is not applicable to default initialisations. Your global declaration of "int *ptr;" does not violate rule 11.9.
