Overview of Clib File Input and Output Methods

Siebel eScript handles file input and file output operations in a way that is similar to the C programming language and the C++ programming language. These languages do not directly read to or write from files. With Siebel eScript, you must first configure the language to open a file. To do this, you typically pass the name of this file to the Clib Open File method.

File input and file output methods in Siebel eScript read the file into a buffer in memory and return a file pointer, which is a pointer that references the beginning of the buffer. The file stream is the data that the buffer contains. Reading and writing occurs relative to the buffer, which is not written to disk unless you explicitly use the Clib Clear Buffer method to clear the buffer or use the Clib Close File method to close the file.
