Detailed Description

Implementing extension plugin parse callback.

Typedef Documentation

typedef LY_ERR(* lyplg_ext_parse_clb)(struct lysp_ctx *pctx, struct lysp_ext_instance *ext)

Callback for parsing extension instance substatements.

All known YANG substatements can easily be parsed using lyplg_ext_parse_extension_instance.

Parameters

[in]	pctx	Parse context.
[in,out]	ext	Parsed extension instance data.

Returns

LY_SUCCESS on success.

LY_ENOT if the extension instance is not supported and should be removed.

LY_ERR error on error.

Function Documentation

LIBYANG_API_DECL LY_ERR lyplg_ext_parse_extension_instance	(	struct lysp_ctx *	pctx,
		struct lysp_ext_instance *	ext
	)

Parse substatements of an extension instance.

Uses standard libyang schema compiler to transform YANG statements into the parsed schema structures. The plugins are supposed to use this function when the extension instance's substatements can be parsed in a standard way.

Parameters

[in]	pctx	Parse context.
[in,out]	ext	Parsed extension instance with the prepared lysp_ext_instance.substmts array, which will be updated by storing the parsed data.

Returns

LY_SUCCESS on success.

LY_ERR error on error.

LIBYANG_API_DECL struct lysp_module* lyplg_ext_parse_get_cur_pmod

(

const struct lysp_ctx *

pctx

)

Get current parsed module from a parse context.

Parameters

[in]

pctx

Parse context.

Returns

Current (local) parse mod.

LIBYANG_API_DECL void lyplg_ext_parse_log	(	const struct lysp_ctx *	pctx,
		const struct lysp_ext_instance *	ext,
		LY_LOG_LEVEL	level,
		LY_ERR	err,
		const char *	format,
			...
	)

Log a message from an extension plugin using the parsed extension instance.

Parameters

[in]	pctx	Parse context to use.
[in]	ext	Parsed extensiopn instance.
[in]	level	Log message level (error, warning, etc.)
[in]	err	Error type code.
[in]	format	Format string to print.
[in]	...	Format variable parameters.
