This video provides a description and example of memcpy() and memset().
- [Instructor] Here we have two very special functions…in string.h which manipulate chunks of bytes in memory.…The first one is memset,…and it writes into the destination buffer…in the first argument, the value in its second argument,…sequentially as many times as specified…in its count argument.…Although the second argument has an integer type,…it is treated as a unsigned char, meaning a single byte.…Now, the second function us memcpy or mem copy,…which copies a source buffer's content…into a destination buffer.…
The number of bytes to copy is specified…in the third argument.…
