STPNCPY(3) Linux Programmer's Manual STPNCPY(3)NAMEstpncpy - copy a fixed-size string, returning a pointer to its end
SYNOPSIS
#define _GNU_SOURCE
#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 VALUEstpncpy() 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.
