Re: Problem with VS and memcpy...

The excat code is:


int number = 25;
int offSet = 16000;
unsigned char header[8];
header[0] = 0;
header[1] = 255;
header[2] = 0;
header[3] = number>>8;
header[4] = number;
header[5] = offSet>>16;
header[6] = offSet>>8;
header[7] = offSet;

memcpy(buffer, header, sizeof header);

Yes I amde some mistakes in the code, I couldn't paste because it was
too long.

Yes, the correct lines are

unsigned char* buffer = new unsigned char[1000];

and

memcpy(buf, temp, sizeof temp);

I didn't use the redundant casts at first, but then I added them, but
nothing changed.

The problem isI just can't see why if I use the debugger before the
memcpy I can see something like

buffer = 0x01234456 "yqhsfjkvdfdsfhfe"

Where "yqhsfjkvdfdsfhfe" ius the content of the buffer, but after
thememcpy it becomes

buffer = 0x01234456 ""

Is it normal?

The content of buffer will only be displayed up until the first terminating
zero. It looks to me like temp has a terminating zero (i.e., '\0') as its
first character.

You need to give us code that actually exhibits the problem (and no other
problem). Code that looks like your code but doesn't have the problem is
useless.
