Function Documentation

nvds_log()

void nvds_log	(	const char *	category,
		int	priority,
		const char *	data,
			...
	)

Logs a message to a location determined by the setup script.

Parameters

[in]	category	A pointer to a string which specifies the category of this message. Categories are user-defined.
[in]	priority	Severity of the event to be logged, based on syslog levels. For more information, see ./src/utils/nvds_logger/README relative to the directory that contains the DeepStream SDK.
[in]	data	A pointer to a string containing the message. The message may contain the format specifiers recognized by printf() in C/C++. data may be followeded by an arbitary number of parameters that supply values for the format specifiers.

nvds_log_close()

void nvds_log_close

(

)

Closes a connection to the logger.

nvds_log_open()

void nvds_log_open

(

)

Opens a connection to the logger.

This function must be called once per DeepStream application execution, prior to use of the logger.
