LIBRARY


.Lb libc

SYNOPSIS


.In string.h void * memcpy void *dst const void *src size_t len

DESCRIPTION

The memcpy function copies len bytes from string src to string dst.

RETURN VALUES

The memcpy function returns the original value of dst.

SEE ALSO

bcopy(3), memccpy(3), memmove(3), strcpy(3), wmemcpy(3)

STANDARDS

The memcpy function conforms to -isoC.

BUGS

In this implementation memcpy is implemented using bcopy(3), and therefore the strings may overlap. On other systems, copying overlapping strings may produce surprises. Programs intended to be portable should use memmove(3) when src and dst may overlap.
