V2002. Consider using the 'Ptr' version of the 'foo' function here.
This diagnostic rule was added at users' request.
The analyzer allows you to detect calls of functions that have 'Ptr' analogues. By this term we mean functions whose name has the 'Ptr' suffix. Some of these extended functions are: 'SetClassLongPtr', 'DSA_GetItemPtr'.
Consider the following source code:
void foo(int a);
void fooPtr(int a, bool b);
....
void test()
{
foo(1); // V2002
}In the fragment where the 'foo' function is called, the V2002 warning will be generated since there is another function with the same name but ending with 'Ptr'. The 'foo2' function does not have an alternative version and therefore no warning will be generated concerning it.
The V2002 message will be also generated in the following case:
void fooA(char *p);
void fooPtrA(char *p, int x);
....
void test()
{
fooA(str); // V2002
}The warning will not be generated if the call of the function with the same name comes from its extended version:
class A
{
....
void foo() { .... };
void fooPtr()
{
foo(); // ok
}
....
};V2001 is a related diagnostic rule.
