Hi my code is as follows char name[100] ; _getcwd(name, (size_t)sizeOfFileName); strcat(name,"\\") ; strcat(name, fileName) ; char *value_str= NULL ; file = fopen(name, "a+"); if(!file) printf("bad file name") ; for(i = 0; i<fileSize ; i++) { value_str = fp_to_str(ddata[i]) ; strLength= strlen(value_str) ; value_str[strLength+...
Lately, I've been working on some small data serialization demos. However, I was wondering how to transfer binary data from a structure into a file descriptor. I am aware that the only (simple) way to do this is through fwrite (if write does this, then please say so), so is there either: A) An fwrite call to use on file descriptors? o...
Hi, I have the following PHP code for writing to a filepointer $fp that was opened using fsockopen: syslog(LOG_INFO, "Write " . strlen($buf) . " bytes to socket:"); $bytes = 0; while ($bytes < strlen($buf) && ($w = @fwrite($fp, substr($buf, $bytes)))) { syslog(LOG_INFO, " - " . $w . " bytes written to socket"); $bytes += $w; }...
I have a config.php file for one of my site which holds information needed to run the site. It somewhat looks like this: <?php $site_name="The Site"; $base_url = "http://site.com"; $upload_path = "/images"; ?> Getting the values from that is easy, I just use require 'config.php'; but how can i give an option to add this from a html ...
I have an existing ini file that I have created and I would like to know if there was a way to update a section of the file or do I have have to rewrite the entire file each time? Here is an example of my config.ini file: [config] title='test' status=0 [positions] top=true sidebar=true content=true footer=false ...
Hi, I am creating pdf document for downloading for e.g. someone clicked a PDF link then a pdf is generated and browser opens new window with path of that pdf file. Problem is that browser is giving 404 NOT found error for that file for about 40-50 seconds after its creation but after that when I refresh browser that file is present for v...
On the php manual we can read: fwrite() returns the number of bytes written Ok... but what kind of thing is "number of bytes written"? Binary string? Binary number? Stream? Int? I'm a little bit lost here. Regards ...
In solaris when I attached dbx to one of the running stacks, I found the call to fwrite leading to __lll_lock_wait()? In what scenario will this happen? Does fwrite internally tries to acquire a lock? ...
What will happen if fwrite & fclose are called in parallel from two threads for the same file descriptor? ...
My code is hanging fwrite with the following stack: libc.so.6.1::___lll_lock_wait libc.so.6.1::fwrite This seems to be happening in solaris. Only incorrect thing which I can think of is that my code may try to do a parallel fclose on the same FILE pointer which is used for doing fwrite. If a parallel fclose happens will it lead to th...
Possible Duplicate: What is the rationale for fread/fwrite taking size and count as arguments? In C, fwrite and fread take both the number of elements to write and the size of each element. It seems like just having a parameter that tells the number of bytes that should be written would more obvious and more general because th...
If I read and write a single file using normal IO APIs, writes are guaranteed to be atomic on a per-block basis. That is, if my write only modifies a single block, the operating system guarantees that either the whole block is written, or nothing at all. How do I achieve the same effect on a memory mapped file? Memory mapped files are ...
When creating a PDF file through PDFlib+PDI, and then write the file with fwrite, all desktop systems can view the contents of the file just fine, but Droid devises can't.... (they only show a blank document in PDF viewer). I'm thinking that, when performing the fwrite, since OS is responsible for determining the file type (based solely ...
I'm using a simple fopen("w") and fwrite setup to write a new file on my server. Recently, this has been arbitrarily assigning 0640 permissions to these files, which means I can't view them from a browser. But it's not happening every time. Can anybody tell me why? What I'm missing here? Here's my code: if ($file=fopen("$filesDir/$yr/$m...
Hi there, I need to export data from mysql to a csv file with column heading but i dont have file permission on the server. Is there any otherway to do it? i.e. using php fwrite? or fputcsv? Any help will be much appriciate. Thanks. ...
Hi all, I have a C function that writes some data to a text file. The data consists of floats, ints and strings. it looks something like this: writeAsTextFile( mystruct_t* myStructWithIntsFloatsAndStrings , const char* fileName); for doing this I use calls to fprintf; Now I would like to write the same data but as binary. I could...
I'm writing this: $fh = fopen('public/newsletter.txt', 'w'); foreach($entries as $row) { fwrite($fh, 'e-mail\n'); fwrite($fh, $row->new_email . ';'); } fclose($fh); Expecting it to be email [email protected]; But I'm getting e-mail\[email protected]; How do I fix this? ...
