stpcpy — copy a string returning a pointer to its end
#define _GNU_SOURCE #include <string.h>
char *stpcpy( |
char *dest, |
const char *src) ; |
The stpcpy
() function copies
the string pointed to by src
(including the terminating
'\0' 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.
stpcpy
() returns a pointer
to the end of the
string dest
(that is,
the address of the terminating null byte) rather than the
beginning.
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.
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); }
