temp_file
Definition: |
string filename = temp_file(string location="", prefix="", extn="tmp", open_mode="")
--or-- {integer fn, string filename} = temp_file( ditto ) -- (if open_mode!="") |
Description: |
Create a temporary filename, which does not already exist, and optionally open it.
location: The directory where the file should be created. If omitted it uses %TEMP% or %TMP%, or C:\temp\ or /tmp/. prefix: the (optional) first part of the filename. extn: the file extension to use, default is "tmp". open_mode: if not "", must be one of "w", "wb", "a", or "ab", in which case it returns an open file handle and string. If open_mode is not provided, there is a 1-in-a-million chance someone else will beat you to the punch; if you do provide one, it will open/loop for you, and return {fn,filename}. In the latter case you are expected to close and delete the file. |
pwa/p2js: | Not supported. |
Example: |
pp(temp_file()) {integer fn, string name} = temp_file("myapp/tmp","data","log","wb") pp({fn,name}) close(fn) {} = delete_file(name) -- output: -- `C:\Users\Pete\AppData\Local\Temp\419750.tmp` -- {3, `C:\Program Files (x86)\Phix\myapp\tmp\data408865.log`} |
