Description
Opens a file specified by Path for reading access. If the path name is valid it will return the handle of the file stream to the file in the files resource manager, if not, it raises an exception. If Shared is true, the file can be accessed by other processes while it is in use by SCAR Divi, if it is false the script gets exclusive access until CloseFile is used to close the file stream. If you wish to write a file you can use the RewriteFile function.
Example
var f: Integer; s: string; begin f := Rewritefile(LogsPath + 'Test.txt', False); WriteFileString(f, 'Hello World!'); CloseFile(f); f := OpenFile(LogsPath + 'Test.txt', False); ReadFileString(f, s, FileSize(f)) WriteLn(s); CloseFile(f); DeleteFile(LogsPath + 'Test.txt'); end.
