## Description

`sd_bus_interface_name_is_valid()` checks if a given string p is a syntactically valid bus interface name. Similarly, `sd_bus_service_name_is_valid()` checks if the argument is a valid bus service name, `sd_bus_member_name_is_valid()` checks if the argument is a valid bus interface member name, and `sd_bus_object_path_is_valid()` checks if the argument is a valid bus object path. Those functions generally check that only allowed characters are used and that the length of the string is within limits.

## Return Value

Those functions return 1 if the argument is a valid interface / service / member name or object path, and 0 if it is not. If the argument is `NULL`, an error is returned.

### Errors

Returned errors may indicate the following problems:

`-EINVAL`

  The p parameter is `NULL`.
