dbus_bool_t dbus_validate_bus_name ( const char *  name,
DBusError error 
)

Check a bus name for validity.

Remember that NULL can always be passed instead of a DBusError *, if you don't care about having an error name and message.

This function is suitable for validating C strings, but is not suitable for validating untrusted data from a network unless the string's length is also checked, since it assumes that the string ends at the first zero byte according to normal C conventions.

Parameters
namea potentially invalid bus name, which must not be NULL
errorerror return
Returns
TRUE if name is valid

dbus_bool_t dbus_validate_interface ( const char *  name,
DBusError error 
)

Check an interface name for validity.

Remember that NULL can always be passed instead of a DBusError *, if you don't care about having an error name and message.

This function is suitable for validating C strings, but is not suitable for validating untrusted data from a network unless the string's length is also checked, since it assumes that the string ends at the first zero byte according to normal C conventions.

Parameters
namea potentially invalid interface name, which must not be NULL
errorerror return
Returns
TRUE if name is valid

dbus_bool_t dbus_validate_member ( const char *  name,
DBusError error 
)

Check a member (method/signal) name for validity.

Remember that NULL can always be passed instead of a DBusError *, if you don't care about having an error name and message.

This function is suitable for validating C strings, but is not suitable for validating untrusted data from a network unless the string's length is also checked, since it assumes that the string ends at the first zero byte according to normal C conventions.

Parameters
namea potentially invalid member name, which must not be NULL
errorerror return
Returns
TRUE if name is valid

dbus_bool_t dbus_validate_path ( const char *  path,
DBusError error 
)

Check an object path for validity.

Remember that NULL can always be passed instead of a DBusError *, if you don't care about having an error name and message.

This function is suitable for validating C strings, but is not suitable for validating untrusted data from a network unless the string's length is also checked, since it assumes that the string ends at the first zero byte according to normal C conventions.

Parameters
patha potentially invalid object path, which must not be NULL
errorerror return
Returns
TRUE if path is valid

dbus_bool_t dbus_validate_utf8 ( const char *  alleged_utf8,
DBusError error 
)

Check a string for validity.

Strings on D-Bus must be valid UTF-8. Remember that NULL can always be passed instead of a DBusError *, if you don't care about having an error name and message.

This function is suitable for validating C strings, but is not suitable for validating untrusted data from a network unless the string's length is also checked, since it assumes that the string ends at the first zero byte according to normal C conventions.

Parameters
alleged_utf8a string to be checked, which must not be NULL
errorerror return
Returns
TRUE if alleged_utf8 is valid UTF-8
