# gss\_inquire\_cred(3)

API function

## NAME

gss\_inquire\_cred - API function

## SYNOPSIS

**#include \<gss.h\>**

**OM\_uint32 gss\_inquire\_cred(OM\_uint32 \*** *minor\_status***, const gss\_cred\_id\_t** *cred\_handle***, gss\_name\_t \*** *name***, OM\_uint32 \*** *lifetime***, gss\_cred\_usage\_t \*** *cred\_usage***, gss\_OID\_set \*** *mechanisms***);**

## ARGUMENTS

- OM\_uint32 \* minor\_status

  (integer, modify) Mechanism specific status code.

- const gss\_cred\_id\_t cred\_handle

  (gss\_cred\_id\_t, read) A handle that refers to the\
     target credential.  Specify GSS\_C\_NO\_CREDENTIAL to inquire about\
     the default initiator principal.

- gss\_name\_t \* name

  (gss\_name\_t, modify, optional) The name whose identity the\
     credential asserts.  Storage associated with this name should be\
     freed by the application after use with a call to\
     **gss\_release\_name()**.  Specify NULL if not required.

- OM\_uint32 \* lifetime

  (Integer, modify, optional) The number of seconds for\
     which the credential will remain valid.  If the credential has\
     expired, this parameter will be set to zero.  If the\
     implementation does not support credential expiration, the value\
     GSS\_C\_INDEFINITE will be returned.  Specify NULL if not required.

- gss\_cred\_usage\_t \* cred\_usage

  (gss\_cred\_usage\_t, modify, optional) How the\
     credential may be used.  One of the following: GSS\_C\_INITIATE,\
     GSS\_C\_ACCEPT, GSS\_C\_BOTH. Specify NULL if not required.

- gss\_OID\_set \* mechanisms

  (gss\_OID\_set, modify, optional) Set of mechanisms\
     supported by the credential.  Storage associated with this OID\
     set must be freed by the application after use with a call to\
     **gss\_release\_oid\_set()**.  Specify NULL if not required.

## DESCRIPTION

Obtains information about a credential.

## RETURN VALUE

\`GSS\_S\_COMPLETE\`: Successful completion.

\`GSS\_S\_NO\_CRED\`: The referenced credentials could not be accessed.

\`GSS\_S\_DEFECTIVE\_CREDENTIAL\`: The referenced credentials were invalid.

\`GSS\_S\_CREDENTIALS\_EXPIRED\`: The referenced credentials have expired.  If the lifetime parameter was not passed as NULL, it will be set to 0.
