warn_any_ptr_int

Controls if the compiler generates a warning message when an integral type is explicitly converted to a pointer type or vice versa.

Syntax

  #pragma warn_any_ptr_int_conv on | off | reset

Remarks

This pragma is useful to identify potential 64-bit pointer portability issues. An example is shown in.

Listing: Example of warn_any_ptr_int_conv

#pragma warn_ptr_int_conv on 
short i, *ip 
void func() { 
 i = (short)ip; 
 /* WARNING: short type is not 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. */ 
}
