unbufcall(9r) unbufcall(9r) NAME unbufcall - STREAMS: Cancels a pending bufcall request SYNOPSIS #include <sys/stream.h> void unbufcall( int id ); ARGUMENTS Specifies a nonzero identifier for the request to be canceled. This nonzero identifier is returned to the module from a previous call to the bufcall interface. DESCRIPTION The unbufcall interface cancels a pending bufcall request. The id argu‐ ment is a nonzero identifier for the request to be canceled. This nonzero identifier is returned to the module from a previous call to the bufcall interface. The unbufcall interface will not return until the pending callback is canceled or has run. Because of this, locks acquired by the callback interface should not be held across the call to unbufcall or a deadlock condition can occur. RETURN VALUES None SEE ALSO Kernel Interfaces: bufcall(9r) unbufcall(9r)[top]
