gOSKextUnresolved

The value to which a kext's unresolved, weakly-referenced symbols are bound.

Declaration

const void *const gOSKextUnresolved;

A kext must test a weak symbol before using it. A weak symbol is only safe to use if it is not equal to gOSKextUnresolved.

Example for a weak symbol named foo:

 
 
      if (&foo != gOSKextUnresolved) {
          foo();
      } else {
          printf("foo() is not supported\n");
      }
