 There are ugly solutions...
 
 in a header file:
 
 #undef fwrite
 
 static inline size_t
 fwrite_checked(const void * restrict ptr, size_t size, size_t nmemb,
     FILE * restrict stream)
 {
 	size_t nw = fwrite(ptr, size, nmemb, stream);
 	assert(nw == nmemb);
 	return nw;
 }
 
 #define fwrite(a, b, c, d) fwrite_checked((a), (b), (c), (d))
