ALcloseport(3dm)					      ALcloseport(3dm)

NAME    [Toc]    [Back]

     ALcloseport - (obsolete) releases resources of an audio port

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/audio.h>

     int ALcloseport(ALport port)

PARAMETER    [Toc]    [Back]

     port   expects the	ALport structure for the audio port you	want to
	    deallocate.	 This structure	is the returned	value of the
	    ALopenport(3dm) call.

DESCRIPTION    [Toc]    [Back]

     ALcloseport is obsolete and is provided for backward compatibility. The
     preferred method of closing an audio port is via alClosePort(3dm).

     ALcloseport(3dm) releases port's resources	back to	the system.  Any
     activity on the port is terminated	when you call ALcloseport(3dm).	 For
     output ports, any samples remaining in the	port will not be output.  For
     input ports, any samples remaining	in the port will be lost.  Since port
     will be deallocated, it should not	be used	in any subsequent audio
     library function calls.

     ALcloseport(3dm) can fail for the following reason:

     AL_BAD_PORT   port	is either invalid or null.

DIAGNOSTICS    [Toc]    [Back]

     Upon successful completion, ALcloseport(3dm) returns 0. Otherwise
     ALcloseport(3dm) returns -1 and sets an error number which	can be
     retrieved using oserror(3C).

DESCRIPTION    [Toc]    [Back]

     alClosePort closes	the given audio	port and frees the associated
