setting memory block with offset

[suni]

HI,

i am trying to use memcpy function with offset in my application. i want to copy bytes from one buffer to the other starting from 3rd location. i want to leave first 2 bytes as header info. Can somebody help me on this please?

Thanks

Just add the offset to the buffers adress ( which is identical to the buffer itself in C ) Something like

memcpy ( target+2, source+2, sizeof( source )-2).

And make sure that the target buffer is big enough.
