Detailed Description
Create/Destroy/Modify a GSI Credential Handle.
Within the Globus GSI Credential Library, all credential operations require a handle
parameter. Currenlty only one operation may be in progress at once per credential handle.
This section defines operations to create, modify and destroy GSI Credential handles.
Typedef Documentation
typedef struct globus_l_gsi_cred_handle_s* globus_gsi_cred_handle_t
GSI Credential Handle. A GSI Credential handle keeps track of state relating to a
credential. Handles can have immutable attributes associated with them. All credential
operations take a credential handle pointer as a parameter.

Function Documentation
globus_result_t globus_gsi_cred_handle_init (globus_gsi_cred_handle_t *handle,
globus_gsi_cred_handle_attrs_thandle_attrs)
Initializes a credential handle to be used credential handling functions. Takes a set of
handle attributes that are immutable to the handle. The handle attributes are only pointed
to by the handle, so the lifetime of the attributes needs to be as long as that of the
handle.
