Detailed Description

Generally, if an application wants to communicate an error from a sysrepo callback, it must return an sr_error_t error value and may optionally set error message using sr_session_set_error_message(). Additionally, if more information needs to be communicated, arbitrary chunks of data can be written by sr_session_push_error_data(), which can then be decoded based on the error format set by sr_session_set_error_format().

To make writing specific errors easier, following is a list of well-known error formats, for which utility functions are provided that allow setting the whole error by a single function.

Well-known error formats:

• NETCONF

Function Documentation

int sr_err_get_netconf_error	(	const sr_error_info_err_t *	err,
		const char **	error_type,
		const char **	error_tag,
		const char **	error_app_tag,
		const char **	error_path,
		const char **	error_message,
		const char ***	error_info_elements,
		const char ***	error_info_values,
		uint32_t *	error_info_count
	)

Get NETCONF callback error.

Parameters

[in]	err	NETCONF error to read.
[out]	error_type	NETCONF error type.
[out]	error_tag	NETCONF error tag.
[out]	error_app_tag	NETCONF error app tag, set to NULL if none.
[out]	error_path	NETCONF error path, set to NULL if none.
[out]	error_message	NETCONF error message.
[out]	error_info_elements	Array of NETCONF error info elements, set to NULL if none.
[out]	error_info_values	Array of NETCONF error info values, set to NULL if none.
[out]	error_info_count	NETCONF error info count of both error_info_elements and error_info_values.

Returns

Error code (SR_ERR_OK on success).

int sr_err_get_netconf_error_idx	(	const sr_error_info_err_t *	err,
		uint32_t	idx,
		const char **	error_type,
		const char **	error_tag,
		const char **	error_app_tag,
		const char **	error_path,
		const char **	error_message,
		const char ***	error_info_elements,
		const char ***	error_info_values,
		uint32_t *	error_info_count
	)

Deprecated, every NETCONF error has its own err, use sr_err_get_netconf_error().

int sr_session_set_netconf_error	(	sr_session_ctx_t *	session,
		const char *	error_type,
		const char *	error_tag,
		const char *	error_app_tag,
		const char *	error_path,
		const char *	error_message,
		uint32_t	error_info_count,
			...
	)

Set NETCONF callback error or add another if a NETCONF error has already been set. Specifically, sets the error message, error format, and error data encoding all the NETCONF-specific error information.

Meaning of each value corresponds to the definiition of NETCONF rpc-error element and value restrictions of error_type and error_tag are checked.

Parameters

[in]	session	Implicit session provided in a callback.
[in]	error_type	NETCONF error type.
[in]	error_tag	NETCONF error tag.
[in]	error_app_tag	Optional NETCONF error app tag.
[in]	error_path	Optional NETCONF error path.
[in]	error_message	NETCONF error message.
[in]	error_info_count	Optional count of elements in NETCONF error info.
[in]	...	Optional NETCONF error info elements. There must be 2x error_info_count parameters. They create pairs of element-name and element-value to be set for the NETCONF error.

Returns

Error code (SR_ERR_OK on success).

int sr_session_set_netconf_error2	(	sr_session_ctx_t *	session,
		const char *	error_type,
		const char *	error_tag,
		const char *	error_app_tag,
		const char *	error_path,
		const char *	error_message,
		uint32_t	error_info_count,
		const char **	error_info_elems,
		const char **	error_info_values
	)

Set NETCONF callback error or add another if a NETCONF error has already been set.

Similar functionality to sr_session_set_netconf_error().

Parameters

[in]	session	Implicit session provided in a callback.
[in]	error_type	NETCONF error type.
[in]	error_tag	NETCONF error tag.
[in]	error_app_tag	Optional NETCONF error app tag.
[in]	error_path	Optional NETCONF error path.
[in]	error_message	NETCONF error message.
[in]	error_info_count	Optional count of elements in NETCONF error info. Also the sizes of error_info_elems and error_info_values.
[in]	error_info_elems	Optional array of NETCONF error info elements.
[in]	error_info_values	Optional array of NETCONF error info values to set for error_info_elems.

Returns

Error code (SR_ERR_OK on success).
