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 aq\0aq character) 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 is not part of the C or POSIX.1 standards, and is
not customary on Unix systems, but is not a GNU invention either.
Perhaps it comes from MS-DOS.
Nowadays, it is also present on the BSDs.
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);
}
BUGS
This function may overrun the buffer
dest.
