Am I missing a more agreeable way to check the return value of a C

pointer to some kind of struct, one has to go through and convert each
instance of NULL to a cast of the appropriate return type. Eg
cast(funnystruct*)0
You can take your pick of these:
if( !ptr ) ...
if( ptr == null ) ...
if( ptr is null ) ...
if ((tomime_fields.fld_description==cast(char*)0))
throw new Exception("show_part_info: description is NULL");
== for value
is for pointers
if (tomime_fields.fld_description is null)
throw new Exception("...");
Actually, while 'is' does work for pointers, it's only necessary for
references.
