XrdOucPinKing< T >::XrdOucPinKing ( const char * drctv, XrdOucEnv & envR, XrdSysError & errR, XrdVersionInfo * vinfo = 0 )

inline

Constructor

Parameters

drctv	Ref to the directive that initiated the load. The text is used in error messages to relate the directive to the error. E.g. "sec.entlib" -> "Unable to load sec.entlib plugin...."
envR	Ref to environment.
errR	Ref to the message routing object.
vinfo	Pointer to the version information of the caller. If the pointer is nil, no version checking occurs.

                     {pinVec.push_back(pinInfo(0,0));}
