|

* Description:
|
||||
* In this kernel mode build, this function will be called to execute a
|
||||
* a signal handler in user-space. When the signal is delivered, a
|
||||
* kernel-mode stub will first run to perform some housekeeping functions.
|
||||
* This kernel-mode stub will then be called transfer control to the user
|
||||
* mode signal handler by calling this function.
|
||||
*
|
||||
* Normally the a user-mode signalling handling stub will also execute
|
||||
* before the ultimate signal handler is called. See
|
||||
* arch/arm/src/armv[6\7]/up_signal_handler. This function is the
|
||||
* user-space, signal handler trampoline function. It is called from
|
||||
* up_signal_dispatch() 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 an architecture specific system call made by up_signal_handler().
|
||||
* However, this will look like a normal return by the caller of
|
||||
* up_signal_dispatch.
