warn_ptr_int_conv

Controls the recognition the conversion of pointer values to incorrectly-sized integral values.

#pragma warn_ptr_int_conv on | off | reset
  

If you enable this pragma, the compiler issues a warning message if an expression attempts to convert a pointer value to an integral type that is not large enough to hold the pointer value.

#pragma warn_ptr_int_conv on

char *my_ptr;
char too_small = (char)my_ptr;  /* WARNING: char is too small. */

See also "warn_any_ptr_int_conv" on page 231.

By default, this pragma is off.
