Functions passed in structs, as args, and init'd

[John/Consultant]

	I have the following code pieces throughout a program:

typedef struct _Astruct{
  int (*myfunc)();
 .
 .
 .
} Astruct;

int
a_function();

then I do the following in a routine:

 .
 .
 .
 Astruct *AS;

  AS->myfunc = (int(*)())NULL;


then later try to change it:

  AS->myfunc = a_function;

But this doesn't work -- I get a segment dump...Am I doing this
wrong??? (It segmentatoin faults at the last C line above.)

Any hints or suggestion, or the err in my ways would be appreciated.
