NAME
       strmaxcpy - copy at most a given number of characters of string

SYNOPSIS
       #include <publib.h>
       char *strmaxcpy(char *tgt, const char *src, size_t n);

DESCRIPTION
       strmaxcpy copies up to n-1 characters from the beginning of src to tgt, then adds a ''.  n must be at least 1.  The target string must be
       large enough to hold the result.

       Note that unlike strncpy(3), this function always terminates the result with ''.  It also doesn't fill the result with extra '' charac-
       ters.

RETURN VALUE
       strmaxcpy returns its first argument.

EXAMPLE
       To  print  out  the  first 69 characters of a string, you might do the following (although familiarity with printf's format string might be
       more useful in this case).

	    #include <stdio.h>
	    #include <publib.h>

	    void print42(const char *string) {
		 char copy[43]; /* 42 + '' */

		 puts(strmaxcpy(copy, string, sizeof(copy)));
	    }
