Detailed Description

Defines the debug logging interface.

The functions of the debugging interface allow clients to receive important debugging information about OpenVX.

See also: vx_status_e for the list of possible errors.

Log messages only can be received after the callback is installed.

Typedefs
typedef void(*	vx_log_callback_f )(vx_context context, vx_reference ref, vx_status status, const vx_char string[])
	The log callback function.

Functions

Function Documentation

void VX_API_CALL vxAddLogEntry	(	vx_reference	ref,
		vx_status	status,
		const char *	message,
			...
	)

Adds a line to the log.

Parameters

[in]	ref	The reference to add the log entry against. Some valid value must be provided.
[in]	status	The status code. `VX_SUCCESS` status entries are ignored and not added.
[in]	message	The human readable message to add to the log.
[in]	...	a list of variable arguments to the message.

Note: Messages may not exceed VX_MAX_LOG_MESSAGE_LEN bytes and will be truncated in the log if they exceed this limit.

void VX_API_CALL vxRegisterLogCallback	(	vx_context	context,
		vx_log_callback_f	callback,
		vx_bool	reentrant
	)

Registers a callback facility to the OpenVX implementation to receive error logs.

Parameters

[in]	context	The overall context to OpenVX.
[in]	callback	The callback function. If NULL, the previous callback is removed.
[in]	reentrant	If reentrancy flag is `vx_true_e`, then the callback may be entered from multiple simultaneous tasks or threads (if the host OS supports this).
