-

i'm trying index of element in array after lfind , bsearch return pointer element found. have far: 

(char *) (found - cv->baseaddress);

where found address of functions found, , base address address of element 0. however, compiler gives me error:

cvector.c:150:28: warning: pointer of type ‘void *’ used in subtraction cvector.c:150:4: warning: return makes integer pointer without cast

what do?

you have typecast returned pointer correct type. need divide offset size of objects in array index.
