.SH "DESCRIPTION"
|
|
.PP
|
|
The
|
|
\fBsd_bus_message_append\fR
|
|
function can be used to append an array of strings to message
|
|
\fIm\fR\&. The parameter
|
|
\fIl\fR
|
|
shall point to a
|
|
\fBNULL\fR\-terminated array of pointers to
|
|
\fBNUL\fR\-terminated strings\&. Each string must satisfy the same constraints as described for the
|
|
"s"
|
|
type in
|
|
\fBsd_bus_message_append_basic\fR(3)\&.
|
|
.PP
|
|
The memory pointed at by
|
|
\fIp\fR
|
|
and the contents of the strings themselves are copied into the memory area containing the message and may be changed after this call\&. Note that the signature of
|
|
\fIl\fR
|
|
parameter is to be treated as
|
|
\fBconst char\ \&*const\ \&*\fR, and the contents will not be modified\&.
|
|
.SH "RETURN VALUE"
|
|
.PP
|
|
On success, this call returns 0 or a positive integer\&. On failure, a negative errno\-style error code is returned\&.
