Mac Forum / Programming / Mac Programming / October 2004Overview of string conversions?
Is there a well-contained overview of the string objects and methods associated with FSSpec and Str255? I am having a terrible time just trying to find out how to convert a char * to an FSSpec. It appears that some string services from the past are no longer supported (e.g. NativePathNameToFSSpec or c2pstr). Thanks. #include <Carbon/Carbon.h> #include <CoreServices/CoreServices.h> int main() { FSSpec fss; char *text = "/tmp/junk.txt"; Str255 name; c2pstr(strcpy((char*)name, text)); /// <-- SEE ERROR [1] OSErr err = FSMakeFSSpec (0, 0, name, &fss); return 0; } [1] 14: implicit declaration of function `int c2pstr(...)' dans l'article r5ahhj-F988A5.15530527102004@newssvr11-ext.news.prodigy.com, r5 à r5ahhj@r5ahhj.bounceme.net a écrit le 27/10/04 22:53 : > Is there a well-contained overview of the string objects > and methods associated with FSSpec and Str255?

FSSpecs expect locale dependant pascal strings, while FSRefs work with UTF-8. Also FSSpecs are imited in name size, and you might encounter mangled names whan they describe a file object with a long name. The only big problem with FSRefs is that you cannot have a FSRef pointing to an inexistant file object. Eric > If you're using unix-style paths, you'd better switch to FSRef api. FSSpecs Is there an equivalent to CreateMovieFile() which accepts FSRef objects? Thanks. Thanks for the help. I found something that works: { FSSpec fss; FSRef ref; char *text = "/tmp/junk.txt"; // // Easy way to force existence of the file to be created. // ofstream ostrm(text); ostrm.close(); OSStatus status = FSPathMakeRef((const UInt8 *) text, &ref, NULL); OSErr err = FSGetCatalogInfo(&ref, kFSCatInfoNone, NULL, NULL, &fss, NULL); } In article <r5ahhj-762BFE.17365027102004@newssvr30-ext.news.prodigy.com>, > Thanks for the help.
