C file size discrepency

由 独自空忆成欢 提交于 2019-12-02 02:37:23
问题 I am trying to learn C, and am currently working on a toy script. Right now, it simply opens a text file, reads it char by char, and spits it out onto the command line. I looked up how to see the size of a file (using fseek() and then ftell()), but the result it returns doesn't match up with the number I get from counting the characters in a while loop as I iterate through the file. I'm wondering if the discrepency is due to windows using \r\n and not just \n, since the discrepency seems to

Reading remote file size using filesize

由 僤鯓⒐⒋嵵緔 提交于 2019-12-02 01:46:10
I read the manual that filesize() is able to calculate file size from remote file. However, when I try to do that with snippet below. I got error PHP Warning: filesize(): stat failed for http://someserver/free_wallpaper/jpg/0000122_480_320.jpg in /tmp/test.php on line 5 Here's my snippet: $file = "http://someserver/free_wallpaper/jpg/0000122_480_320.jpg"; echo filesize( $file ); Turns out, I can't use HTTP for filesize(). Case close. I'll use snippet here as a work-around solution. filesize doesn't work for HTTP - it depends on stat , which isn't supported for the HTTP(S) protocol . The PHP

How to use size of file inside Ant target

由 十年热恋 提交于 2019-12-01 18:15:12
I'm currently in the process of replacing my homebrewn build script by an Ant build script. Now I need to replace various tokens by the size of a specific file. I know how to get the size in bytes via the <length> task and store in in a property, but I need the size in kilobytes and megabytes too. How can I access the file size in other representations (KB, MB) or compute these values from within the Ant target and store them in a property? Edit: After I discovered the <script> task, it was fairly easy to calculate the other values using some JavaScript and add a new property to the project

Paperclip attachment file size

由 北慕城南 提交于 2019-12-01 18:14:54
How do I fetch the file size of each style of a paperclip attachment? @user.attachment_file_size doesn't seem to work @user.attachment(:style).size gives a number not related to the actual file size I didn't find either how to get the file size for a given style , other than the original one. As seen in the paperclip source code , @user.attachment.size returns the size of the file as originally assigned. There is no way to get it for a specific style... A solution would be: open(@user.attachment(:style)).size But not efficient at all. To do it well, you should probably add some "custom size"

Compiled C++ executables HUGE?

由 限于喜欢 提交于 2019-12-01 18:09:59
问题 After programming for a while in C, I decided to finally start to learn C++. This is sort of bothering me, as the standard 'hello world' in C is usually ~16KB, including all of the crud your compiler throws on there. (Using stdio) However, when I create a C++ executable doing hello world, the file is ~470KB! I went ahead and used cstdio instead of iostream, thinking it would make a difference and it did. My question is: When I include iostream, why does the size of my executable explode? Edit

PHP: get remote file size with strlen? (html)

由 本小妞迷上赌 提交于 2019-12-01 10:34:54
I was looking at PHP docs for fsockopen and whatnot and they say you can't use filesize() on a remote file without doing some crazy things with ftell or something (not sure what they said exactly), but I had a good thought about how to do it: $file = file_get_contents("http://www.google.com"); $filesize = mb_strlen($file) / 1000; //KBs, mb_* in case file contains unicode Would this be a good method? It seemed so simple and good to use at the time, just want to get any thoughts if this could run into problems or not be the true file size. I only wish to use this on text (websites) by the way

MongoDB GridFS File Sizes huge for relatively small file

由 不羁岁月 提交于 2019-12-01 09:40:36
问题 I'm doing some tests to see whether we can use GridFS on MongoDB to store files for a future application; I'm using 10gen's C# driver to "Upload" an 80Mb file onto the database. The first addition was fine and took approx 3 seconds which isn't too bad on my test machine; however future additions of the same file took much longer, up to 30 seconds eventually MongoDB told me it ran out of memory and crashed out. Adding 10 files, 80Mb in size results in 8 files being created for my database

Warning : filesize function failing to operate [closed]

The Following Code: <?php $filevar = "/images/staunton/{$options_item['base_var']}.gif"; if(filesize($filevar) > 1616){ $setstatus = "enabled"; } else{ $setstatus = "disabled"; } ?> Results in: Warning: filesize() [function.filesize]: stat failed for /images/staunton/3-25.gif in [Originating PHPFILE(Edited)] on line 24 The Path is the correct file.... my hosting server is running php 5.2 - is this a synax error? I've been looking at similar code and it seems to look correct. Instead of this: $filevar = "/images/staunton/{$options_item['base_var']}.gif"; you probably want: $filevar = $_SERVER[
