Description [src]

Execute request subaction of transaction to the given node according to given code. When the response subaction arrives and running event dispatcher reads the contents, HinawaFwReq::responded signal handler is called.

Parameters

node

Type: HinawaFwNode

A HinawaFwNode.

The data is owned by the caller of the function.

tcode

Type: HinawaFwTcode

A transaction code of HinawaFwTcode.

addr

Type: guint64

A destination address of target device.

length

Type: gsize

The range of address in byte unit.

frame

Type: An array of guint8*

An array with elements for byte data. Callers should give it for buffer with enough space against the request since this library performs no reallocation. Due to the reason, the value of this argument should point to the pointer to the array and immutable. The content of array is mutable for read and lock transaction.

The argument will be modified by the function.

The length of the array is specified in the frame_size argument.

The instance takes ownership of the data, and is responsible for freeing it.

frame_size

Type: gsize*

The size of array in byte unit. The value of this argument should point to the numeric number and mutable for read and lock transaction.

The argument will be modified by the function.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will left initialized to NULL by the method if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
