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 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.
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.
