RPC_GSS_MECH_TO_OID(3NSL) Networking Services Library Functions
rpc_gss_mech_to_oid, rpc_gss_qop_to_num - map mechanism, QOP strings
to non-string values
#include <rpc/rpcsec_gss.h>
bool_t rpc_gss_mech_to_oid(charc*mech, rpc_gss_OIDc*oid);
bool_t rpc_gss_qop_to_num(char *qop, char *mech, u_int *num);
Because in-kernel RPC routines use non-string values for mechanism
and Quality of Protection (QOP), these routines exist to map strings
for these attributes to their non-string counterparts. (The non-
string values for QOP and mechanism are also found in the
/etc/gss/qop and /etc/gss/mech files, respectively.)
rpc_gss_mech_to_oid() takes a string representing a mechanism, as
well as a pointer to a rpc_gss_OID object identifier structure. It
then gives this structure values corresponding to the indicated
mechanism, so that the application can now use the OID directly with
RPC routines. rpc_gss_qop_to_num() does much the same thing, taking
strings for QOP and mechanism and returning a number.
Information on RPCSEC_GSS data types for parameters may be found on
the rpcsec_gss(3NSL) man page.
mech
An ASCII string representing the security mechanism in use.
Valid strings may be found in the /etc/gss/mech file.
oid
An object identifier of type rpc_gss_OID, whose elements are
usable by kernel-level RPC routines.
qop
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 /etc/gss/qop.
num
The non-string value for the QOP.
Both functions return TRUE if they are successful, FALSE otherwise.
/etc/gss/mech
File containing valid security mechanisms
/etc/gss/qop

NAME
rpc_gss_mech_to_oid, rpc_gss_qop_to_num - map mechanism, QOP strings
to non-string values
SYNOPSIS
#include <rpc/rpcsec_gss.h>
bool_t rpc_gss_mech_to_oid(charc*mech, rpc_gss_OIDc*oid);

DESCRIPTION
Because in-kernel RPC routines use non-string values for mechanism

for these attributes to their non-string counterparts. (The non-
string values for QOP and mechanism are also found in the
/etc/gss/qop and /etc/gss/mech files, respectively.)
rpc_gss_mech_to_oid() takes a string representing a mechanism, as
well as a pointer to a rpc_gss_OID object identifier structure. It
then gives this structure values corresponding to the indicated
mechanism, so that the application can now use the OID directly with
