Function Documentation

settings_name_next()

int settings_name_next	(	const char *	name,
		const char **	next
	)

#include <zephyr/settings/settings.h>

determine the number of characters before the first separator

Parameters

[in]	name	in string format
[out]	next	pointer to remaining of name (excluding separator)

Returns

index of the first separator, in case no separator was found this is the size of name

settings_name_steq()

int settings_name_steq	(	const char *	name,
		const char *	key,
		const char **	next
	)

#include <zephyr/settings/settings.h>

Compares the start of name with a key.

Parameters

[in]	name	in string format
[in]	key	comparison string
[out]	next	pointer to remaining of name, when the remaining part starts with a separator the separator is removed from next

Some examples: settings_name_steq("bt/btmesh/iv", "b", &next) returns 1, next="t/btmesh/iv" settings_name_steq("bt/btmesh/iv", "bt", &next) returns 1, next="btmesh/iv" settings_name_steq("bt/btmesh/iv", "bt/", &next) returns 0, next=NULL settings_name_steq("bt/btmesh/iv", "bta", &next) returns 0, next=NULL

REMARK: This routine could be simplified if the settings_handler names would include a separator at the end.

Returns

0: no match 1: match, next can be used to check if match is full
