fileReadAll

 

 

Overview

The fileReadAll function reads the entire contents of the specified path and file name {filePathName}, and returns the result as a ByteVector.

Usage

The fileReadAll function is used to read the entire contents of a file into memory. For instance the following Lisp code shows how to read the contents of the test.txt file into memory. Notice how the _path variable is appended to the file name to make sure that a full path and file name are passed to the fileReadAll function.

(setq fileContents (fileReadAll (append _path "/" test.txt"))) ;; Read the contents of test.txt

 

Syntax

Expression:(fileReadAll filePathName) ;; Reads the entire contents of the specified path and file name

Arguments Name Type Description
Argument:filePathNameString Text The path and file name to be read.

Returns: Returns a ByteVector with the entire contents of the specified file
