Function Documentation

osl_acceptPipe()

SAL_DLLPUBLIC oslPipe osl_acceptPipe

(

oslPipe

Pipe

)

osl_acquirePipe()

SAL_DLLPUBLIC void osl_acquirePipe

(

oslPipe

Pipe

)

Increases the refcount of the pipe.

Parameters

[in]

Pipe

pipe handle

See also

osl_releasePipe

osl_closePipe()

SAL_DLLPUBLIC void osl_closePipe

(

oslPipe

Pipe

)

Close the pipe.

Any read, write or accept actions stop immediately.

Parameters

[in]

Pipe

pipe handle

See also

osl_createPipe

osl_createPipe()

SAL_DLLPUBLIC oslPipe osl_createPipe	(	rtl_uString *	strPipeName,
		oslPipeOptions	Options,
		oslSecurity	Security )

Create or open a pipe.

Parameters

[in]	strPipeName	pipe name
[in]	Options	create or open the pipe
[in]	Security	pipe creator

Returns

nullptr on failure, otherwise returns the pipe handle

See also

osl_closePipe

osl_getLastPipeError()

SAL_DLLPUBLIC oslPipeError osl_getLastPipeError

(

oslPipe

Pipe

)

osl_readPipe()

SAL_DLLPUBLIC sal_Int32 osl_readPipe	(	oslPipe	Pipe,
		void *	pBuffer,
		sal_Int32	BufferSize )

Reads blocking from the pipe.

Returns

Number of read bytes. If less than BufferSize, the pipe was closed.

osl_receivePipe()

SAL_DLLPUBLIC sal_Int32 osl_receivePipe	(	oslPipe	Pipe,
		void *	pBuffer,
		sal_Int32	BufferSize )

osl_releasePipe()

SAL_DLLPUBLIC void osl_releasePipe

(

oslPipe

Pipe

)

Decreases the refcount of the pipe.

If the refcount drops to zero, the handle is destroyed.

Parameters

[in]

Pipe

pipe handle

osl_acquirePipe

osl_sendPipe()

SAL_DLLPUBLIC sal_Int32 osl_sendPipe	(	oslPipe	Pipe,
		const void *	pBuffer,
		sal_Int32	BufferSize )

osl_writePipe()

SAL_DLLPUBLIC sal_Int32 osl_writePipe	(	oslPipe	Pipe,
		const void *	pBuffer,
		sal_Int32	BufferSize )

Writes blocking onto the pipe.

Returns

Number of written bytes. If less than BufferSize, the pipe was closed.
