    1.18 +* FUNCTION
    1.19 +* <<strncat>>---concatenate strings
    1.20 +* INDEX
    1.21 +* strncat
    1.22 +* ANSI_SYNOPSIS
    1.23 +* #include <string.h>
    1.24 +* char *strncat(char *<[dst]>, const char *<[src]>, size_t <[length]>);
    1.25 +* TRAD_SYNOPSIS
    1.26 +* #include <string.h>
    1.27 +* char *strncat(<[dst]>, <[src]>, <[length]>)
    1.28 +* char *<[dst]>;
    1.29 +* char *<[src]>;
    1.30 +* size_t <[length]>;
    1.31 +* <<strncat>> appends not more than <[length]> characters from
    1.32 +* the string pointed to by <[src]> (including the	terminating
    1.33 +* null character) to the end of the string pointed to by
    1.34 +* <[dst]>.  The initial character of <[src]> overwrites the null
    1.35 +* character at the end of <[dst]>.  A terminating null character
    1.36 +* is always appended to the result
    1.37 +* WARNINGS
    1.38 +* Note that a null is always appended, so that if the copy is
    1.39 +* limited by the <[length]> argument, the number of characters
    1.40 +* appended to <[dst]> is <<n + 1>>.
    1.41 +* RETURNS
    1.42 +* This function returns the initial value of <[dst]>
    1.43 +* PORTABILITY
    1.44 +* <<strncat>> is ANSI C.
    1.45 +* <<strncat>> requires no supporting OS subroutines.

    1.57 +Append substring to string.
    1.58 +Appends num characters of src string to dest string. 
    1.59 +If the terminating null-character appears in src string 
    1.60 +before num character have been appended, the function appends 
    1.61 +the null-character to dest and ends.
    1.62 +The terminating null character in dest is overwritten by the first character of src.
    1.63 +The resulting string includes a null-character at end.
    1.64 +@return s1 is returned

    1.66 +plus num characters. 
    1.67 +@param s2 Null-terminated string containing characters to be appended. 
    1.68 +@param n Number of characters to be appended from src to dest.
