NAME

6       stpncpy - copy a fixed-size string, returning a pointer to its end
7

SYNOPSIS

9       #define _GNU_SOURCE
10       #include <string.h>
11
12       char *stpncpy(char *dest, const char *src, size_t n);
13

DESCRIPTION

15       The  stpncpy()  function  copies  at  most n characters from the string
16       pointed to by src, including the terminating  '\0'  character,  to  the
17       array  pointed  to  by dest.  Exactly n characters are written at dest.
18       If the length strlen(src) is smaller than n, the  remaining  characters
19       in  the  array  pointed to by dest are filled with '\0' characters.  If
20       the length strlen(src) is greater or equal to n, the string pointed  to
21       by dest will not be '\0' terminated.
22
23       The strings may not overlap.
24
25       The programmer must ensure that there is room for at least n characters
26       at dest.
27

RETURN VALUE

29       stpncpy() returns a pointer to the terminating null  in  dest,  or,  if
30       dest is not null-terminated, dest + n.
31
