HinawaFwFcpavc_transaction

Declaration [src]
gboolean
hinawa_fw_fcp_avc_transaction (
HinawaFwFcp* self,
const guint8* cmd,
gsize cmd_size,
guint8** resp,
gsize* resp_size,
guint timeout_ms,
GError** error
)
Description [src]
Finish the pair of asynchronous transaction for AV/C command and response. The timeout_ms
parameter is used to wait for response transaction since the command transaction is initiated.
The timeout is not expanded in the case that AV/C INTERIM status arrived, thus the caller should
expand the timeout in advance for the case.
Available since: 4.0
Parameters
cmd
-
Type: An array of
guint8
An array with elements for request byte data. The value of this argument should point to the array and immutable.
The length of the array is specified in the cmd_size
argument.The data is owned by the caller of the function. cmd_size
-
Type:
gsize
The size of array for request in byte unit.
resp
-
Type: An array of
guint8*
An array with elements for response 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.
The argument will be modified by the function. The length of the array is specified in the resp_size
argument.The instance takes ownership of the data, and is responsible for freeing it. resp_size
-
Type:
gsize*
The size of array for response in byte unit. The value of this argument should point to the numerical number and mutable.
The argument will be modified by the function. timeout_ms
-
Type:
guint
The timeout to wait for response transaction since command transactions finishes.
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 aNULL
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.
