The function load_json_from_file() loads a JSON object from a file located in the specified directory. It returns a parsed JSON object if successful, or NULL if the file does not exist or an error occurs.

C

Prototype

json_t *load_json_from_file(
    hgobj gobj,
    const char *directory,
    const char *filename,
    log_opt_t on_critical_error
);

Parameters

Key	Type	Description
`gobj`	`hgobj`	A handle to a GObj, used for logging errors.
`directory`	`const char *`	The directory where the JSON file is located.
`filename`	`const char *`	The name of the JSON file to be loaded.
`on_critical_error`	`log_opt_t`	Logging options to handle critical errors.

Return Value

Returns a json_t * object containing the parsed JSON data if successful, or NULL if the file does not exist or an error occurs.

The function uses json_loadfd() to parse the JSON file. If the file does not exist, it returns NULL without logging an error. If an error occurs while opening or parsing the file, it logs an error message using gobj_log_critical().
