STPNCPY(3)                 Linux Programmer's Manual                STPNCPY(3)



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

SYNOPSIS
       #include <string.h>

       char *stpncpy(char *dest, const char *src, size_t n);

DESCRIPTION
       The  stpncpy  function  copies  at  most  n  characters from the string
       pointed to by src, including the terminating  '\0'  character,  to  the
       array  pointed to by dest. Exactly n characters are written at dest. If
       the length strlen(src) is smaller than n, the remaining  characters  in
       the  array  pointed  to by dest are filled with '\0' characters. If the
       length strlen(src) is greater or equal to n, the string pointed  to  by
       dest will not be '\0' terminated.

       The strings may not overlap.

       The programmer must ensure that there is room for at least n characters
       at dest.

RETURN VALUE
       stpncpy returns a pointer to the terminating null in dest, or, if  dest
       is not null-terminated, dest + n.

CONFORMING TO
       This function is a GNU extension.
