STPCPY(3) Linux Programmer's Manual STPCPY(3)
stpcpy - copy a string returning a pointer to its end
char *stpcpy(char *dest, const char *src);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
Since glibc 2.10:
_XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
Before glibc 2.10:
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 desti-
nation 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 ter-
minating null byte) rather than the beginning.
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.
This function may overrun the buffer dest.
For example, this program uses stpcpy() to concatenate foo and bar to produce foobar,
which it then prints.
char *to = buffer;
to = stpcpy(to, "foo");
to = stpcpy(to, "bar");
