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.
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.
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.
