---

SYNOPSIS#include <systemd/sd−bus​.h>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);

---

DESCRIPTIONsd_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 VALUEThose 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​.

---

ErrorsReturned errors may indicate the following problems: −EINVAL The p parameter is NULL​.

---

NOTESThese APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd ​pkg-config(1) file​.
