Re: strcpy and strcat's return type

Why do strcpy and strcat (and strupr and strlwr in some nonstandard
implementations) return a char*? Surely the logical (and DMA-safe)
)return type for these would have been void??


Why should strcat() return a void *, when both of it's arguments are
char *, and the function is defined as working on character strings?


He said void, not void *. And to answer the actual question: I think,
they return char * to allow such things as

  return strcat(strcpy(buf, path), file);
