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:
           _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 destination 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 terminating null byte) rather than the beginning.

ATTRIBUTES

   For   an   explanation   of   the  terms  used  in  this  section,  see
   attributes(7).

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);
   }
