Input/Output The Open Function

The open() function opens a new file handle

File handles can be opened for reading or writting

The syntax of the open() function is

$err = open( FILEHANDLENAME, EXPR );

  • FILEHANDLENAME is the name you wish to use for the filehandle

  • EXPR is the filename you wish to open

But, how do you specify that a file handle opened for reading VS writing...
