Имя (Name)

sd_bus_interface_name_is_valid, sd_bus_service_name_is_valid,
       sd_bus_member_name_is_valid, sd_bus_object_path_is_valid - Check
       if a string is a valid bus name or object path

Синопсис (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);

Описание (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.

---

Возвращаемое значение (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.
