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.
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.
Returned errors may indicate the following problems:
The p parameter is NULL.
Added in version 246.
Functions described here are available as a shared library, which can be compiled against and linked to with the libsystemd pkg-config(1) file.
The code described here uses getenv(3), which is declared to be not multi-thread-safe. This means that the code calling the functions described here must not call setenv(3) from a parallel thread. It is recommended to only do calls to setenv() from an early phase of the program when no other threads have been started.
sd_bus_interface_name_is_valid(), sd_bus_service_name_is_valid(), sd_bus_member_name_is_valid(), and sd_bus_object_path_is_valid() were added in version 246.

The man pages sd_bus_member_name_is_valid(3), sd_bus_object_path_is_valid(3) and sd_bus_service_name_is_valid(3) are aliases of sd_bus_interface_name_is_valid(3).
