MEMCPY(3) BSD Library Functions Manual MEMCPY(3)NAME
memcpy -- copy memory area
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h>
void *
memcpy(void *restrict dst, const void *restrict src, size_t n);
DESCRIPTION
The memcpy() function copies n bytes from memory area src to memory area dst. If dst and src overlap, behavior is undefined. Applications
in which dst and src might overlap should use memmove(3) instead.
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 ISO/IEC 9899:1990 (``ISO C90'').

bcmp, bcopy, bzero, memccpy, memchr, memcmp, memcpy, memmove, memset -- byte string operations
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h>
int
bcmp(const void *b1, const void *b2, size_t len);
void
bcopy(const void *src, void *dst, size_t len);
void
bzero(void *b, size_t len);
void *
memchr(const void *b, int c, size_t len);
int
memcmp(const void *b1, const void *b2, size_t len);
void *
memccpy(void *dst, const void *src, int c, size_t len);
void *
memcpy(void *dst, const void *src, size_t len);
void *
memmove(void *dst, const void *src, size_t len);
void *
memset(void *b, int c, size_t len);
DESCRIPTION
These functions operate on variable length strings of bytes. They do not check for terminating null bytes as the routines listed in
string(3) do.
See the specific manual pages for more information.
SEE ALSO bcmp(3), bcopy(3), bzero(3), memccpy(3), memchr(3), memcmp(3), memcpy(3), memmove(3), memset(3)STANDARDS
The functions memchr(), memcmp(), memcpy(), memmove(), and memset() conform to ISO/IEC 9899:1990 (``ISO C90'').
HISTORY
The functions bzero() and memccpy() appeared in 4.3BSD; the functions bcmp(), bcopy(), appeared in 4.2BSD.

Hi
Having a lil trouble with a rather simple application I'm writing. It so happens that I have to copy some data using memcpy() and so far I've been doing just fine compiling it with VC.Net and running it on Windows XP.

Dear All,
I am trying to compile OpenFOAM-1.7.x in RHEL. I could not able to compile some of the applications because of libc version issues.
It is saying
undefined reference to memcpy@GLIBC_2.14
Can anybody look into it?
Thanks & Regards,
