typedef enum { ... } SilcSKRStatus;

    Indicates the status of the key repository procedures.  This is
    returned to SilcSKRFindCallback function to indicate the status
    of the finding.  This is a bitmask, and more than one status may
    be set at one time.

    If there are no errors only SILC_SKR_OK is set.  If error occurred
    then at least SILC_SKR_ERROR is set, and possibly other error
    status also.

    If the SILC_SKR_UNSUPPORTED_TYPE is returned the repository does not
    support the public key type and it cannot be added to the repository.

    typedef enum {
      SILC_SKR_OK                 = 0x00000001, /* All is Ok */
      SILC_SKR_ERROR              = 0x00000002, /* Generic error status */
      SILC_SKR_ALREADY_EXIST      = 0x00000004, /* Key already exist */
      SILC_SKR_NOT_FOUND          = 0x00000008, /* No keys were found */
