.SH NAME
fmodsw \- STREAMS module declaration structure
.SH SYNOPSIS
.nf
#include <sys/stream.h>
#include <sys/conf.h>
.fi

.SH INTERFACE LEVEL
illumos DDI specific (illumos DDI)
.SH DESCRIPTION
The \fBfmodsw\fR structure contains information for STREAMS modules. All
STREAMS modules must define a \fBfmodsw\fR structure.
.sp
.LP
\fBf_name\fR must match \fBmi_idname\fR in the \fBmodule_info\fR structure. See
\fBmodule_info\fR(9S). \fBf_name\fR should also match the module binary name.
(See WARNINGS.)
.sp
.LP
All modules must set the \fBf_flag\fR to \fBD_MP\fR to indicate that they
safely allow multiple threads of execution. See \fBmt-streams\fR(9F) for
additional flags.
