This pragma is useful to identify potential pointer portability issues. An example is

shown in Listing C.20

Listing C.20 Example of warn_any_ptr_int_conv

#pragma warn_ptr_int_conv on

short i, *ip

void foo() {

i = (short)ip; // WARNING: integral type is not large

// large enough to hold pointer

}

#pragma warn_any_ptr_int_conv on

void bar() {

i = (int)ip; // WARNING: pointer to integral

// conversion

ip = (short *)i; // WARNING: integral to pointer

// conversion

}
