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.
For example, this program uses stpcpy() to concatenate “foo” and “bar” to produce “foobar”, which it then prints.
#include <string.h> int main (void) { char *to = buffer; to = stpcpy(to, "foo"); to = stpcpy(to, "bar"); printf("%s\n", buffer); }
