SD_BUS_INTERFACE_NAME_IS_VALID(3)               sd_bus_interface_name_is_valid

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.

           Added in version 246.

NOTES
       Functions described here are available as a shared library, which can
       be compiled against and linked to with the libsystemd pkg-config(1)
       file.

       The code described here uses getenv(3), which is declared to be not
       multi-thread-safe. This means that the code calling the functions
       described here must not call setenv(3) from a parallel thread. It is
       recommended to only do calls to setenv() from an early phase of the
       program when no other threads have been started.

HISTORY
       sd_bus_interface_name_is_valid(), sd_bus_service_name_is_valid(),
       sd_bus_member_name_is_valid(), and sd_bus_object_path_is_valid() were
       added in version 246.
