Mac Forum / Programming / Mac Programming / September 2006Copying files om Mac OS... please Help! XCode!
I'm trying to copy file on the same volume, File is a shared library; in the source directory it's size 16 Kbytes. After copying it's size 6 KB, and it has type Excel file!!! ))) And it's doesn't work! Procedure: OSStatus DoStupidCopy(char *pszSrcPath, char *pszDestDir) { static const int iBufSize= 4*4096; char pBuf[iBufSize]; FILE* fSource = fopen(pszSrcPath,"rb"); if (!fSource) return 1;//throw "Can't open file"; FILE* fTarget = fopen(pszDestDir,"wb"); if (!fTarget) return 1;//throw "Can't write file"; int len; while ( len = fread( pBuf, sizeof(char), iBufSize, fSource ) ) { fwrite(pBuf, sizeof(char), len, fTarget); } fclose(fSource); fclose(fTarget); return noErr; } I've spent a lot of time to learn how to use MoreFilesX but I can't do anything with it. Beforehand thanks. > I'm trying to copy file on the same volume, > File is a shared library; in the source directory it's size 16 Kbytes. [quoted text clipped - 28 lines] > > Beforehand thanks. From the man page for fread: --------------- The functions fread() and fwrite() advance the file position indicator for the stream by the number of bytes read or written. They return the number of objects read or written. If an error occurs, or the end-offile is reached, the return value is a short object count (or zero). The function fread() does not distinguish between end-of-file and error, and callers must use feof(3) and ferror(3) to determine which occurred. The function fwrite() returns a value less than nmemb only if a write error has occurred. --------------- Please rewrite your example to properly check the return values of fread and fwrite, and if you still have a problem, ask again. Also, don't forget Bundles (folders that the Finder presents as a single, file-like object. For example, .framework files), and resource forks. > From the man page for fread: > --------------- [quoted text clipped - 15 lines] > single, file-like object.

This file in Midnight commander is present as one file, and it's size 6 KB but in finder 16! After copying in MC it's size still 6 KB and in finder too!

This code works well in debugger... Source file size 6190 destination file size 6190, in finder 16 KB! Have Mac OS some function which I can use And copy it successful??? Also I tried to use: status = ::PBHCopyFileSync(¶mBlock) ; But I got status is -50 for local volume. Thanks. I've found this: Incidentally, FSCopyObject does not work correctly on 10.4 -- it does not copy HSF+ Extended Attributes -- so the correct solution here is to call FSCopyObjectSync from the OS on 10.4 and later, and only use the FSCopyObject sample code on 10.3.
