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

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

SYNOPSIS
       #include 

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

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

       stpcpy():
           Since glibc 2.10:
               XOPENSOURCE >= 700 || POSIXCSOURCE >= 200809L
           Before glibc 2.10:
               GNUSOURCE

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.

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, but was
       not a GNU invention either.  Perhaps it came from MS-DOS.  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 GNUSOURCE
           #include 
           #include 

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

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