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.
