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 ' ' 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 ' ' characters. If the length strlen(src) is greater or equal to n, the string pointed to by dest
will not be ' ' 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.
