Arrays containing names of value components. These are read-only.
@FCGI_TYPE_NAME
    print $FCGI_TYPE_NAME[FCGI_BEGIN_REQUEST]; # FCGI_BEGIN_REQUEST
    
@FCGI_ROLE_NAME
    print $FCGI_ROLE_NAME[FCGI_RESPONDER]; # FCGI_RESPONDER
    
@FCGI_PROTOCOL_STATUS_NAME
    print $FCGI_PROTOCOL_STATUS_NAME[FCGI_OVERLOADED]; # FCGI_OVERLOADED
    
Note
It's not safe to assume that "exists" works for validation purposes, index 0 might be "undef".
Use boolean context instead:
    ($FCGI_TYPE_NAME[$type])
      || die;

None by default. All functions can be exported using the ":all" tag or individually.
