- * Name: signal_handler
- *
- * Description:
- *   This function is the user-space, signal handler trampoline function.  It
- *   is called from up_signal_handler() in user-mode.
- *
- * Inputs:
- *   sighand - The address user-space signal handling function
- *   signo, info, and ucontext - Standard arguments to be passed to the
- *     signal handling function.
- *
- * Return:
- *   None.  This function does not return in the normal sense.  It returns
- *   via signal_handler_return (see include/nuttx/arch.h)
