STPCPY(3)                           Linux Programmer's Manual                           STPCPY(3)



NAME
       stpcpy - copy a string returning a pointer to its end

SYNOPSIS
       #include <string.h>

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

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       stpcpy():
           Since glibc 2.10:
               _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
           Before glibc 2.10:
               _GNU_SOURCE

DESCRIPTION
       The  stpcpy() function copies the string pointed to by src (including the terminating null
       byte ('\0')) to the array pointed to by dest.  The strings may not overlap, and the desti‐
       nation string dest must be large enough to receive the copy.

RETURN VALUE
       stpcpy() returns a pointer to the end of the string dest (that is, the address of the ter‐
       minating null byte) rather than the beginning.

ATTRIBUTES
   Multithreading (see pthreads(7))
       The stpcpy() function is thread-safe.

CONFORMING TO
       This function was added to POSIX.1-2008.  Before that, it was not part of the C or POSIX.1
       standards, nor customary on UNIX systems.  It first appeared at least as early as 1986, in
       the Lattice C AmigaDOS compiler, then in the GNU fileutils and GNU textutils in 1989,  and
       in the GNU C library by 1992.  It is also present on the BSDs.

BUGS
       This function may overrun the buffer dest.

EXAMPLE
       For  example,  this  program  uses  stpcpy() to concatenate foo and bar to produce foobar,
       which it then prints.

       #define _GNU_SOURCE
       #include <string.h>
       #include <stdio.h>

       int
       main(void)
       {
           char buffer[20];
           char *to = buffer;

           to = stpcpy(to, "foo");
           to = stpcpy(to, "bar");
           printf("%s\n", buffer);
       }
