#include <gssapi/gssapi.h>
This call is intended for use by applications that communicate over protocols that impose a maximum message size. It enables the application to fragment messages prior to applying protection.
GSS-API implementations are recommended but not required to detect invalid QOP values when gss_wrap_size_limit() is called. This routine guarantees only a maximum message size, not the availability of specific QOP values for message protection.
Successful completion of this call does not guarantee that gss_wrap(3) will be able to protect a message of length max_input_size bytes, since this ability may depend on the availability of system resources at the time that gss_wrap(3) is called. However, if the implementation itself imposes an upper limit on the length of messages that may be processed by gss_wrap, the implementation should not return a value via max_input_bytes that is greater than this length.
| minor_status | Mechanism specific status code. |
| context_handle | A handle that refers to the security over which the messages will be sent. |
| conf_req_flag | Indicates whether gss_wrap(3) will be asked to apply confidentiality protection in addition to integrity protection. |
| qop_req | Indicates the level of protection that gss_wrap(3) will be asked to provide. |
| req_output_size | |
| The desired maximum size for tokens emitted by gss_wrap(3). | |
| max_input_size | The maximum input message size that may be presented to gss_wrap(3) in order to guarantee that the emitted token shall be no larger than req_output_size bytes. |
| GSS_S_COMPLETE | Successful completion. |
| GSS_S_NO_CONTEXT | The referenced context could not be accessed. |
| GSS_S_CONTEXT_EXPIRED | |
| The context has expired. | |
| GSS_S_BAD_QOP | The specified QOP is not supported by the mechanism. |
