## Function Documentation

SAL_DLLPUBLIC oslPipe osl_acceptPipe | ( | oslPipe | Pipe | ) |

SAL_DLLPUBLIC void osl_acquirePipe | ( | oslPipe | Pipe | ) |

increases the refcount of the pipe.

SAL_DLLPUBLIC void osl_closePipe | ( | oslPipe |  | ) |

closes the pipe, any read,write or accept actions stop immeadiatly.

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

SAL_DLLPUBLIC oslPipeError osl_getLastPipeError | ( | oslPipe | Pipe | ) |

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.

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

SAL_DLLPUBLIC void osl_releasePipe | ( | oslPipe |  | ) |

decreases the refcount of the pipe.

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

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

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.
