strins

   NAME
    strins - insert one string within another

   SYNOPSIS
    void strins(d, s);
    char *d;
    const char *s;

   FUNCTION
    strins inserts string s into d by shifting the string in d over
    strlen(s) spaces and then copying s into the newly made hold (except
    for the nul, of course).  This result is s inserted into d.

   NOTE
    There must be enough room in d to insert s.  i.e. if d is an array
    of 32 chars and contains a string of 8 chars you can insert another
    string of, say, 10 chars, but not of 30 chars.

    strins is NOT an ANSI standard function

   EXAMPLE
    #include <stdio.h>
    #include <string.h>

    main()
    {
        char buf[32];

        strcpy(buf, "This is a test");
        strins(buf + 5, "<gak!> ");
        puts(buf);      /*  This <gak!> is a test   */

        return(0);
    }

   INPUTS
    char *d;        destination to insert in front of
    char *s;        source string to insert

   RESULTS
    none
