请教两个函数

samplise

最近在看一段开源代码（在linux下运行），有两个函数marshall_int32和unmarshall_int32。从程序中看应该是系统函数，但我用在shell下用man没有找到，google和baidu上的信息也很少，不知道是否有人知道，望告知。

data marshalling Last modified: Tuesday, June 12, 2001   


  
  
The process of gathering data and transforming it into a standard format before it is transmitted over a network so that the data can transcend network boundaries. In order for an object to be moved around a network, it must be converted into a data stream that corresponds with the packet structure of the network transfer protocol. This conversion is known as data marshalling. Data pieces are collected in a message buffer before they are marshaled. When the data is transmitted, the receiving computer converts the marshaled data back into an object.
Data marshalling is required when passing the output parameters of a program written in one language as input to a program written in another language.
