Function Documentation

kernel_get_num_rpc_funcs()

size_t kernel_get_num_rpc_funcs

(

pid_t

pid

)

Get the number of RPC functions a process has registers

Parameters

pid	The PID of the process

Returns

the number of RPC functions the process has registered

kernel_rpc_call()

void* kernel_rpc_call	(	pid_t	pid,
		char *	name,
		void *	buf,
		size_t	size
	)

Call an RPC function

Parameters

pid	The PID of the process with the RPC function
name	The name of the function to call
buf	The argument buffer to provide
size	The size of the argument buffer

Returns

the return buffer of the RPC functiom

kernel_rpc_deallocate_buf()

void kernel_rpc_deallocate_buf	(	void *	buf,
		size_t	size
	)

Deallocate an RPC return buffer

Parameters

buf	The buffer to deallocate
size	The size of the buffer to deallocate

kernel_rpc_mark_as_init()

void kernel_rpc_mark_as_init

(

)

Mark the current process as ready to accept RPC calls

kernel_rpc_register_func()

void kernel_rpc_register_func	(	char *	name,
		rpc_func	code
	)

Register an RPC function

Parameters

name	The name of the function
code	The code of the function

kernel_rpc_return()

void kernel_rpc_return	(	void *	buf,
		size_t	size
	)

Set the RPC return buffer for the calling thread & unblock the calling thread

Parameters

buf	The return buffer
size	The size of the return buffer

Note

This function must only be called from an RPC thread
