I am using PIC 18f252 for my proj. I am using memory copy function to swap data between two locations and hit with error.

My function is:
Code:
memmove(&uid[uid_index], &uid[uid_index + 1], 3);

error: undefined identifier: memmove

you need to include string.h

You will find that memmove is listed under the string functions, which have the comment that you need to include this, but if you go directly to the 'memmove' manual entry, it forgets to tell you this.....
