NAME

librock_strn0cpy - copy at most n characters, always appending a \0.

#License - #Source code - #Example Use -

SYNOPSIS

#include <librock/parse.h>

char *
librock_strn0cpy(
    char *dest,
    const char *src,
    int n
);

DESCRIPTION

Copy the smaller of (strlen(src), n) characters from src to dest, always appending a '\0' onto dest. This is a well-behaved work-alike for strncpy. Remember that n+1 bytes at dest will be affected if strlen(src) >= n.

Returns the first argument. This does not '\0' fill dest[> strlen(src)] as some strncpy implementations do.

Typical use is to replace clumsy two-step calls to strncpy such as:

     strncpy(dest,src,sizeof(dest));
     dest[sizeof(dest)-1] = '\0';

with:

     librock_strn0cpy(dest,src,sizeof(dest-1));

If you don't want the '\0', then use memmove()
