:I just found it - the function is called |strpcpy()|:
:-- snip --
:NAME
: stpcpy - copy a string returning a pointer to the end of the
:destination
:
:SYNOPSIS
: char *ptr = stpcpy(d, s);
: char *d;
: char *s;
:
:FUNCTION
: Copy the nul terminated string pointed to by s to the buffer d.
: The nul is copied. A pointer to the nul character at the end
: of the copied string in d is returned.
:
:NOTE
: stpcpy() is a non-standard function. While a stpcpy()/stpcpy()
: combination is more efficient than a strcpy()/strcat() combination,

:Note: This extension is already available in Linux - the only thing ToDo

:propose it to the standard bodies (which ones ?) ...

Heh. Interesting! It looks like it originally came from Linux, back
in the day when string scanning ops actually ate a significant amount
of cpu. I've included an excerpt from Apple's manual page for it from
Darwin below.
So I guess if you need it for linux portability... but generally
speaking, unbounded string functions such as stpcpy() (strcpy(),
strncpy() due to its mishandling of nul, strcat(), etc) should be
avoided in all new code and anyone still using those functions
should be soundly rapped on the head. To make code auditing easier,
we remove all uses of such functions from our source base whenever we
see them, even if there is no chance of an overflow.

http://developer.apple.com/documentation/Darwin/Reference/Manpages/man3/stpcpy.3.html]
STANDARDS
The strcpy() and strncpy() functions conform to ISO/IEC 9899:1990
(``ISO C90''). The stpcpy() function is an MS-DOS and GNUism. The
stpcpy() function conforms to no standard.
HISTORY
The stpcpy() function first appeared in FreeBSD 4.4, coming from
1998-vintage Linux.
