int sd_bus_interface_name_is_valid(const char* p);

int sd_bus_service_name_is_valid(const char* p);

int sd_bus_member_name_is_valid(const char* p);

int sd_bus_object_path_is_valid(const char* p);

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​.

Functions described here are available as a shared library, which can be compiled against and linked to with the libsystemd ​pkg-config(1) file​.

All functions listed here are thread-agnostic and only a single thread may operate on a given object at any given time​. Different threads may access the same object at different times​. Multiple independent objects may be used from different threads in parallel​.

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​.
