NAME         top

       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         top

       #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         top

       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         top

       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.

       Returned errors may indicate the following problems:

           The p parameter is NULL.

           Added in version 246.

NOTES         top

       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

HISTORY         top

       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.
