Utility Operations

xIsProtocol

Returns true if the XObj is a protocol.

bool xIsProtocol ( XObj )

xIsSession

Returns true if the XObj is a session.

bool xIsSession ( XObj )

xIsXObj

Returns true if the XObj is either a session or a protocol (i.e., if this returns false the XObj was either never initialized or has been badly clobbered.)

bool xIsXObj ( XObj )

xIsValidXObj

XObjects created with xCreateSessn or xCreateProtl are kept in a system map and removed when the object is destroyed. xIsValidXObj can be used to determine whether a random XObject handle is in this map and can thus be used safely.

bool xIsValidXObj ( XObj )

xPrintXObj

Displays some information about the state of the XObj.

bool xPrintXObj ( XObj )
