    unireg_end()

    This function never returns.

901

902 903 904 905
    If SIGNALS_DONT_BREAK_READ is defined, this function is called
    by the main thread. To get MySQL to shut down nicely in this case
    (Mac OS X) we have to call exit() instead if pthread_exit().

/*
  Initialize all MySQL global variables to default values

  SYNOPSIS
    mysql_init_variables()

  NOTES
    The reason to set a lot of global variables to zero is to allow one to
    restart the embedded server with a clean environment
    It's also needed on some exotic platforms where global variables are
    not set to 0 when a program starts.

    We don't need to set numeric variables refered to in my_long_options
    as these are initialized by my_getopt.
