gss_release_buffer(3GSS) Generic Security Services API Library Functions gss_release_buffer(3GSS)NAME
gss_release_buffer - free buffer storage allocated by a GSS-API function
SYNOPSIS
cc -flag ... file ...-lgss [library ...]
#include <gssapi/gssapi.h>
OM_uint32 gss_release_buffer(OM_uint32 *minor_status, gss_buffer_tbuffer);
DESCRIPTION
The gss_release_buffer() function frees buffer storage allocated by a GSS-API function. The gss_release_buffer() function also zeros the
length field in the descriptor to which the buffer parameter refers, while the GSS-API function sets the pointer field in the descriptor to
NULL. Any buffer object returned by a GSS-API function may be passed to gss_release_buffer(), even if no storage is associated with the
buffer.
PARAMETERS
The parameter descriptions for gss_release_buffer() follow:
minor_status Mechanism-specific status code.
buffer The storage associated with the buffer will be deleted. The gss_buffer_desc() object will not be freed; however, its
length field will be zeroed.
ERRORS
The gss_release_buffer() function may return the following status codes:
GSS_S_COMPLETE Successful completion
GSS_S_FAILURE The underlying mechanism detected an error for which no specific GSS status code is defined. The mechanism-spe-
cific status code reported by means of the minor_status parameter details the error condition.

gss_get_mic(3GSS) Generic Security Services API Library Functions gss_get_mic(3GSS)NAME
gss_get_mic - calculate a cryptographic message
SYNOPSIS
cc [ flag... ] file... -lgss [ library... ]
#include <gssapi/gssapi.h>
OM_uint32 gss_get_mic(OM_uint32 *minor_status,
const gss_ctx_id_t context_handle, gss_qop_t qop_req,
const gss_buffer_t message_buffer, gss_buffer_t msg_token);
DESCRIPTION
The gss_get_mic() function generates a cryptographic MIC for the supplied message, and places the MIC in a token for transfer to the peer
application. The qop_req parameter allows a choice between several cryptographic algorithms, if supported by the chosen mechanism.
Since some application-level protocols may wish to use tokens emitted by gss_wrap(3GSS) to provide secure framing, the GSS-API allows MICs
to be derived from zero-length messages.
PARAMETERS
The parameter descriptions for gss_get_mic() follow:
minor_status The status code returned by the underlying mechanism.
context_handle Identifies the context on which the message will be sent.
qop_req Specifies the requested quality of protection. Callers are encouraged, on portability grounds, to accept the default
quality of protection offered by the chosen mechanism, which may be requested by specifying GSS_C_QOP_DEFAULT for this
parameter. If an unsupported protection strength is requested, gss_get_mic() will return a major_status of GSS_S_BAD_QOP.
message_buffer The message to be protected.
msg_token The buffer to receive the token. Storage associated with this message must be freed by the application after use with a
call to gss_release_buffer(3GSS).
ERRORS
gss_get_mic() may return the following status codes:
GSS_S_COMPLETE Successful completion.
GSS_S_CONTEXT_EXPIRED The context has already expired.
GSS_S_NO_CONTEXT The context_handle parameter did not identify a valid context.
GSS_S_BAD_QOP The specified QOP is not supported by the mechanism.
GSS_S_FAILURE The underlying mechanism detected an error for which no specific GSS status code is defined. The mechanism-spe-
cific status code reported by means of the minor_status parameter details the error condition.
