ColdFusion 8: Added this function.
Parameter |
Description |
---|---|
fileobj |
The file to close. |
You should always close a file after opening it. When you use the FileOpen function to open a file, the file stream from the disk is opened and contents are read from or written to it. The FileClose function closes the stream. If you do not close a file, the stream remains open; in that case, the operating system can lock the file, which results in the file not being usable until the server is restarted.
The following example checks to see if a file is still open and closes it.
<cfscript> myfile = FileOpen("c:\ColdFusionScorpio\wwwroot\test1.txt", "read"); while(NOT FileIsEOF(myfile)) { x = FileReadLine(myfile); WriteOutput("#x# <br>"); } </cfscript> <!--- Additional code goes here. ---> <cfif #myfile.status# IS "open"> <cfoutput>The file #myfile.filepath# is #myfile.status#</cfoutput><br> <cfscript> FileClose(myfile); </cfscript> </cfif>
