SD_BUS_...S_VALID(3) sd_bus_interface_name_is_valid SD_BUS_...S_VALID(3)
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
#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);
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.
Errors
Returned errors may indicate the following problems:
-EINVAL
The p parameter is NULL.
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.
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.
