Tcl_CreateCloseHandler(3TCL) Tcl Library Procedures Tcl_CreateCloseHandler(3TCL) __________________________________________________________________________________________________________________________________________________NAMETcl_CreateCloseHandler, Tcl_DeleteCloseHandler - arrange for callbacks when channels are closedSYNOPSIS#include <tcl.h> void Tcl_CreateCloseHandler(channel, proc, clientData) void Tcl_DeleteCloseHandler(channel, proc, clientData)ARGUMENTSTcl_Channel channel (in) The channel for which to create or delete a close callback. Tcl_CloseProc *proc (in) The procedure to call as the callback. ClientData clientData (in) Arbitrary one-word value to pass to proc. _________________________________________________________________DESCRIPTIONTcl_CreateCloseHandler arranges for proc to be called when channel is closed with Tcl_Close or Tcl_UnregisterChannel, or using the Tcl close command. Proc should match the following prototype: typedef void Tcl_CloseProc( ClientData clientData); The clientData is the same as the value provided in the call to Tcl_CreateCloseHandler. Tcl_DeleteCloseHandler removes a close callback for channel. The proc and clientData identify which close callback to remove; Tcl_Delete- CloseHandler does nothing if its proc and clientData arguments do not match the proc and clientData for a close handler for channel.SEE ALSOclose(1T), Tcl_Close(3TCL), Tcl_UnregisterChannel(3TCL)KEYWORDScallback, channel closingATTRIBUTESSee attributes(5) for descriptions of the following attributes: +--------------------+-----------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +--------------------+-----------------+ |Availability | SUNWTcl | +--------------------+-----------------+ |Interface Stability | Uncommitted | +--------------------+-----------------+NOTESSource for Tcl is available on http://opensolaris.org.
