.SH "DESCRIPTION"
.PP
\fBsd_bus_interface_name_is_valid()\fR
checks if a given string
\fIp\fR
is a syntactically valid bus interface name\&. Similarly,
\fBsd_bus_service_name_is_valid()\fR
checks if the argument is a valid bus service name,
\fBsd_bus_member_name_is_valid()\fR
checks if the argument is a valid bus interface member name, and
\fBsd_bus_object_path_is_valid()\fR
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\&.
.SH "RETURN VALUE"
.PP
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\&.
.SS "Errors"

Returned errors may indicate the following problems:

\fB\-EINVAL\fR
.RS 4
The
\fIp\fR
parameter is
