Question

I am trying to convert a short array into a bytearray in qt.
is there any function available to do the casting.
if i have to use const char * for conversion how should i do it.
and is there any better way than to use reinterpret cast

Thanks in advance.

Answer 1

You can convert an array of short to bytes simply by casting a byte pointer to the short array

short s[10];
unsigned char *p = reinterpret_cast<unsigned char*>(s);

then use the pointer to go through all the bytes in the array where you copy the *p to a byte array if u wish.

for ( unsigned char *p = reinterpret_cast<unsigned char*>(s); 
      p < s + sizeof(s); 
      ++p)
{...}
