.IX \f4unfreezestr\fP(D3DK)

NAME

unfreezestr − unfreeze the state of a stream

SYNOPSIS

#include <sys/types.h>
#include <sys/stream.h>
void unfreezestr(queue_t ∗q, pl_t pl);

ARGUMENTS

qPointer to a message queue. 

plThe interrupt priority level to be set (if the implementation requires that interrupts be blocked in order to prevent deadlock) after unfreezing the stream.  See LOCK_ALLOC(D3DK) for a list of valid values for pl.  pl should be the value that was returned from the corresponding call to freezestr(D3DK) unless the caller has a specific need to set some other interrupt priority level.  Although portable drivers must always specify an appropriate pl argument, implementations which do not require that the interrupt priority level be raised while the stream is frozen may choose to ignore this argument. 

DESCRIPTION

With the current release of STREAMs, it is no longer necessary to freeze/unfreeze a stream.  The freezestr/unfreezestr calls in the current implementation of STREAMs are stub routines which provide backward compatibility for old modules which used these calls.
