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

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);

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.

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.

NOTES

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