# memccpy(3)

copy string until character found

## NAME

**memccpy** – copy string until character found

## LIBRARY

Standard C Library (libc, -lc)

## SYNOPSIS

**#include \<string.h\>**

*void* *\**\

**memccpy**(*void \*restrict dst*, *const void \*restrict src*, *int c*, *size\_t n*);

## DESCRIPTION

The **memccpy**() function copies bytes from string *src* to string *dst*. If the character *c* (as converted to an unsigned char) occurs in the string *src*, the copy stops and a pointer to the byte after the copy of *c* in the string *dst* is returned. Otherwise, *n* bytes are copied, and a NULL pointer is returned.

The source and destination strings should not overlap, as the behavior is undefined.

## SEE ALSO

[bcopy(3)](/bcopy/3.md), [memcpy(3)](/memcpy/3.md), [memmove(3)](/memmove/3.md), [strcpy(3)](/strcpy/3.md)

## HISTORY

The **memccpy**() function first appeared in 4.4BSD.
