.SH DESCRIPTION
.sp
.LP
\fBrpc_gss_seccreate()\fR is used by an appliction to create a security context
using the \fBRPCSEC_GSS\fR protocol, making use of the underlying \fBGSS-API\fR
network layer.   \fBrpc_gss_seccreate()\fR allows an application to specify the
type of security mechanism (for example, Kerberos v5), the type of service (for
example, integrity checking), and the Quality of Protection (\fBQOP\fR) desired
for transferring data.
.SH PARAMETERS
.sp
.LP
Information on  \fBRPCSEC_GSS\fR data types for parameters may be found on the
\fBrpcsec_gss\fR(3NSL) man page.
.sp
.ne 2
.mk
.na
\fB\fIclnt\fR\fR
.ad
.RS 16n
.rt  
This is the RPC client handle. \fIclnt\fR may be obtained, for example, from
\fBclnt_create()\fR.
.RE

.sp
.ne 2
.mk
.na
\fB\fIprincipal\fR\fR
.ad
.RS 16n
.rt  
This is the identity of the server principal, specified in the form
\fIservice\fR@\fIhost\fR, where \fIservice\fR is the name of the service the
client wishes to access and \fIhost\fR is the fully qualified name of the host
where the service resides \(em for example, nfs@mymachine.eng.company.com.
.RE

.sp
.ne 2
.mk
.na
\fB\fImechanism\fR\fR
.ad
.RS 16n
.rt  
This is an ASCII string which indicates which security mechanism to use with
this data.  Appropriate mechanisms may be found in the file
\fB/etc/gss/mech\fR; additionally, \fBrpc_gss_get_mechanisms()\fR returns a
list of supported security mechanisms (as null-terminated strings).
.RE

.sp
.ne 2
.mk
.na
\fB\fIservice_type\fR\fR
.ad
.RS 16n
.rt  
This sets the initial type of service for the session \(em privacy, integrity,
authentication, or none.
.RE

.sp
.ne 2
.mk
.na
\fB\fIqop\fR\fR
.ad
.RS 16n
.rt  
This is an ASCII string which sets the quality of protection (QOP) for the
session. Appropriate values for this string may be found in the file
\fB/etc/gss/qop\fR. Additionally, supported QOPs are returned (as
null-terminated strings) by \fBrpc_gss_get_mech_info()\fR.
.RE

.sp
.ne 2
.mk
.na
\fB\fIoptions_req\fR\fR
.ad
.RS 16n
.rt  
This structure contains options which are passed directly to the underlying
\fBGSS_API\fR layer.  If the caller specifies \fINULL\fR for this parameter,
defaults are used. (See  \fBNOTES\fR, below.)
.RE

.sp
.ne 2
.mk
.na
\fB\fIoptions_ret\fR\fR
.ad
.RS 16n
.rt  
These \fBGSS-API\fR options are returned to the caller. If the caller does not
need to see these options, then it may specify \fINULL\fR for this parameter.
(See \fBNOTES,\fR below.)
.RE

.SH RETURN VALUES
.sp
.LP
\fBrpc_gss_seccreate()\fR returns a security context handle (an RPC
authentication handle) of type \fBAUTH\fR. If \fBrpc_gss_seccreate()\fR cannot
return successfully, the application can get an error number by calling
\fBrpc_gss_get_error()\fR.
