-FUNCTION
- <<stpcpy>>---copy string returning a pointer to its end
-
-INDEX
- stpcpy
-
-ANSI_SYNOPSIS
- #include <string.h>
- char *stpcpy(char *<[dst]>, const char *<[src]>);
-
-TRAD_SYNOPSIS
- #include <string.h>
- char *stpcpy(<[dst]>, <[src]>)
- char *<[dst]>;
- char *<[src]>;
-
-DESCRIPTION
- <<stpcpy>> copies the string pointed to by <[src]>
- (including the terminating null character) to the array
- pointed to by <[dst]>.
-
-RETURNS
- This function returns a pointer to the end of the destination string,
- thus pointing to the trailing '\0'.
-
-PORTABILITY
-<<stpcpy>> is a GNU extension, candidate for inclusion into POSIX/SUSv4.
-
-<<stpcpy>> requires no supporting OS subroutines.
