Some sites out there do not have BSD 4.3 or Sys V. Those of you who do will find the compiler will complain about a routine called memcpy. This is basically a blockmove call. If you have that, use it. If not, here is memcpy from a string package posted few months back. /* * memcpy - copy bytes */ char *memcpy(dst, src, size) char *dst; char *src; int size; { register char *d; register char *s; register int n; if (size <= 0) return(dst); s = src; d = dst; if (s <= d && s + (size-1) >= d) { /* Overlap, must copy right-to-left. */ s += size-1; d += size-1; for (n = size; n > 0; n--) *d-- = *s--; } else for (n = size; n > 0; n--) *d++ = *s++; return(dst); }
