   stpcpy    ( 3 )

Имя (Name)

stpcpy - copy a string returning a pointer to its end

---

Синопсис (Synopsis)

#include <string.h>

       char *stpcpy(char *restrict dest, const char *restrict 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

---

Описание (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.

---

Возвращаемое значение (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.

Стандарты (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.

---

Ошибки (баги) (Bugs)

This function may overrun the buffer dest.

---

Примеры (Examples)

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);
       }
