11 char *stpcpy(char *dest, const char *src);

13 Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
14
15 stpcpy():
16 Since glibc 2.10:
17 _POSIX_C_SOURCE >= 200809L
18 Before glibc 2.10:
19 _GNU_SOURCE
20
22 The stpcpy() function copies the string pointed to by src (including
23 the terminating null byte ('\0')) to the array pointed to by dest. The
24 strings may not overlap, and the destination string dest must be large
25 enough to receive the copy.
26
28 stpcpy() returns a pointer to the end of the string dest (that is, the
29 address of the terminating null byte) rather than the beginning.

41 This function was added to POSIX.1-2008. Before that, it was not part
42 of the C or POSIX.1 standards, nor customary on UNIX systems. It first
43 appeared at least as early as 1986, in the Lattice C AmigaDOS compiler,
44 then in the GNU fileutils and GNU textutils in 1989, and in the GNU C
45 library by 1992. It is also present on the BSDs.
46
48 This function may overrun the buffer dest.
49
51 For example, this program uses stpcpy() to concatenate foo and bar to
52 produce foobar, which it then prints.
