NAME
rpc_gss_get_mechanisms(), rpc_gss_get_mech_info(), rpc_gss_get_versions(), rpc_gss_is_installed() - get information on mechanisms and RPC
version
SYNOPSIS
DESCRIPTION
These "convenience functions" return information on available security mechanisms and versions of
Returns a list of supported security mechanisms as a null-terminated
list of character strings.
Takes two arguments: an ASCII string representing a mechanism type
(for example, and a pointer to a will return NULL upon error or if no file is present. Otherwise, it returns a null-terminated list
of character strings of supported Quality of Protections (QOPs) for this mechanism. NULL or empty list implies only that the
default QOP is available and can be specified to routines that need to take a QOP string parameter as NULL or as an empty string.
Returns the highest and lowest versions of
supported.
Takes an ASCII string representing a mechanism, and returns
if the mechanism is installed.
PARAMETERS
Information on data types for parameters may be found on the rpcsec_gss(3N) manpage.
mech An ASCII string representing the security mechanism in use. Valid strings may also be found in the file.
service A pointer to a representing the current security service (privacy, integrity, or none).
vers_hi, vers_lo
The highest and lowest versions of supported.
MULTITHREAD USAGE
Thread Safe: Yes
Cancel Safe: Yes
Fork Safe: No
Async-cancel Safe: No
Async-signal Safe: No
These functions can be called safely in a multithreaded environment. They may be cancellation points in that they call functions that are
cancel points.
In a multithreaded environment, these functions are not safe to be called by a child process after and before These functions should not be
called by a multithreaded application that supports asynchronous cancellation or asynchronous signals.
BUGS
The service argument for is currently irrelevant.
FILES
File containing valid security mechanisms.
File containing valid QOP values.
