using fopen and fwrite

[sfullman]

Hi All,

Quick question, during an import process I want to open (create) and write to several status files - this process runs for hours sometimes and this is helpful if the process fails.

What switch do I use for fopen('file.tx', '?') so that every time I call fwrite(), it overwrites everything and starts the file over?

In other words, I don't want to append in this case.

thanks, Sam

the "w" second argument to [man]fopen[/man] will truncate the file to zero length. this however will not affect mulitiple calls to [man]fwrite[/man] using the same opned handle. i suggest that you call [man]fopen[/man] again when you want to re-trucate the file back to zero.
