.TH SERVICE_PROVIDER.CONF 5 "Jun 18, 2004"
.SH NAME
service_provider.conf \- service provider configuration file
.SH SYNOPSIS
.LP
.nf
\fBservice_provider.conf\fR
.fi

.SH DESCRIPTION
.LP
\fBservice_provider.conf\fR contains information about the device type that the
service provider supports. This information includes the pathname of the
service provider library, the library version and other library characteristics
that are required by the system administrative command, \fBdatadm\fR(8).
\fBdatadm\fR(8) puts this information in the DAT static register file,
\fBdat.conf\fR(5).
.sp
.LP
The \fBdatadm\fR program enumerates each device entry into a list of interface
adapters, that is, interfaces to external network that are available to uDAPL
consumers. This new list of interface adapters is appended to other service
providers' information in the DAT static registry, \fBdat.conf\fR. You can do
this if you invoke the \fBdatadm\fR program with the \fB-a\fR option and the
pathname of the \fBservice_provider.conf\fR file.
.sp
.LP
Each entry in the service_provider.conf is a single line of 7 fields.
.sp
.LP
The following shows the order of the fields in a \fBservice_provider.conf\fR
entry:
.sp
.in +2
.nf
"\fIdriver_name\fR" "\fIAPI_version\fR" "\fIthreadsafe_library\fR | \e
      \fInonthreadsafe_library\fR"\e
"\fIdefault_version\fR | \fInondefault_version\fR" \e
     "\fIservice_provider_library_pathname\fR"\e
"\fIservice_provider_version\fR" "\fIservice_provider_instance_data\fR"\e
.fi
.in -2

.sp
.LP
The fields are defined as follows:
.sp
.ne 2
.na
\fB\fIdriver_name\fR\fR
.ad
.sp .6
.RS 4n
Specifies a driver name in the format of \fBdriver_name\fR=\fIvalue pair\fR,
for example, \fBdriver_name=tavor\fR.
.RE

.sp
.ne 2
.na
\fB\fIAPI_version\fR\fR
.ad
.sp .6
.RS 4n
Specifies the API version of the service provider library: For example,
\fB"u"major.minor\fR is \fBu1.2\fR.
.RE

.sp
.ne 2
.na
\fB\fIthreadsafe_library\fR | \fInonthreadsafe_library\fR\fR
.ad
.sp .6
.RS 4n
Specifies a threadsafe or non-threadsafe library.
.RE

.sp
.ne 2
.na
\fB\fIdefault_version\fR | \fInondefault_version\fR\fR
.ad
.sp .6
.RS 4n
Specifies a default or non-default version of a library. A service provider can
offer several versions of the library. If so, one version is designated as
\fBdefault\fR with the rest as \fBnondefault\fR.
.RE

.sp
.ne 2
.na
\fB\fIservice_provider_library_pathname\fR\fR
.ad
.sp .6
.RS 4n
Specifies the pathname of the library image.
.RE

.sp
.ne 2
.na
\fB\fIservice_provider_version\fR\fR
.ad
.sp .6
.RS 4n
Specifies the version of the service provider. By convention, specify the
company stock symbol as the service provider, followed by major and minor
version numbers, for example, \fBSUNW1.0\fR.
.RE

.sp
.ne 2
.na
\fB\fIservice_provider_instance_data\fR\fR
.ad
.sp .6
.RS 4n
Specifies the service provider instance data.
