Detailed Description

Defines the debug logging interface.

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

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.

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).
