lws_settings_plat_get()

LWS_VISIBLE LWS_EXTERN int lws_settings_plat_get	(	lws_settings_instance_t *	si,
		const char *	name,
		uint8_t *	dest,
		size_t *	max_actual
	)

lws_settings_plat_get() - read a named blob from a settings instance

Parameters

si	the settings instance
name	the name of the setting blob in the instance
dest	NULL, or the buffer to copy the setting blob info
max_actual	point to size of dest, or zero; actual blob size on exit

If the named blob doesn't exist in the si, or can't read, returns nonzero. Otherwise, returns 0 and sets *max_actual to the true blob size. If dest is non-NULL, as much of the blob as will fit in the amount specified by *max_actual on entry is copied to dest.

lws_settings_plat_set()

LWS_VISIBLE LWS_EXTERN int lws_settings_plat_set	(	lws_settings_instance_t *	si,
		const char *	name,
		const uint8_t *	src,
		size_t	len
	)

lws_settings_plat_get() - read a named blob from a settings instance

Parameters

si	the settings instance
name	the name of the setting blob in the instance
src	blob to copy to settings instance
len	length of blob to copy

Creates or replaces a settings blob of the given name made up of the len bytes of data from src.

lws_settings_plat_printf()

LWS_VISIBLE LWS_EXTERN int lws_settings_plat_printf	(	lws_settings_instance_t *	si,
		const char *	name,
		const char *	format,
			...
	)

lws_settings_plat_printf() - read a named blob from a settings instance

Parameters

si	the settings instance
name	the name of the setting blob in the instance
format	printf-style format string

Creates or replaces a settings blob of the given name from the printf-style format string and arguments provided. There's no specific limit to the size, the size is computed and then a temp heap buffer used.

lws_settings_init()

LWS_VISIBLE LWS_EXTERN lws_settings_instance_t* lws_settings_init	(	const lws_settings_ops_t *	so,
		void *	opaque_plat
