## Escape Sequences
C has a standard for processing different escape sequences. Many languages built with C in mind parse these escape sequences in a similar way.
* `\ooo`: Consists of one to three octal digits.
* [[bash/index|Bash]] supports this sequence as `$'\ooo'`.

How are C escape sequences for octal digits denoted?
Back: As `\ooo`.

## Copying Functions
The two primary functions used for copying memory are `memcpy` and `memmove`:

void* memcpy(void* restrict s1, const void* restrict s2, size_t n);
void* memmove(void* s1, const void* s2, size_t n);
