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

       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.
