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.


Примечание (Note)

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