stpncpy - copy a fixed-size string, returning a pointer to its end
Návod, kniha: Linux Programmer's Manual
#define _GNU_SOURCE
#include <string.h>
char *stpncpy(char *dest, const char *src, size_t n);
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.
stpncpy returns a pointer to the terminating null in
dest, or, if
dest is not null-terminated,
dest + n.
This function is a GNU extension.
