search for: ftell

Hi, I'm stumped. How can I do ftell and fseek in R? (Where ftell gives the position in the file and fseek points the file pointer to a given position.)

Greetings one and all; I'm not subscribed to this list so I'm first sending this message to verify that mails from me make it through, and then later I'll send the juicy messages with patches. Also, the address I'm using is IPv6-only and doesn't often work, so drop me from any replies and I'll catch the archives, or drop only the hostname part to get an IPv4 address that

...of _seek_helper, and I'm not sure it's correct. _seek_helper is declared static (which I also changed for my convenience to match the above), and is not available to be used elsewhere. However, in the process of building `ogg123', I found that I needed to replace references to fseek()/ftell() with something comparable to the above -- otherwise I'd need to duplicate the below in order to use the proper function. It may be that the above should not be available to be used elsewhere, in which case the above should be `static' and I'll need to work on later hacks. Come to thi...

The PE headers of the generated efi file were quite buggy. And since OVMF perform a few consistency checks, syslinux was unable to run on it. I don't pretend to have a thorough understanding of the PE+ headers, some bugs may remain. :) Celelibi (4): efi: Fix PE header field rva_and_sizes_nr efi: Location, size and alignment of .text section efi: Useless relocations in PE file efi: PE

...opy/pasting it into another program, seems to rather wasteful, and vorbisfile does everything that a decoder needs. More than 95% of the vorbisfile code doesn't actually care about the underlying data source, however. Looking through it, we see a total of 4 functions called: fread() fseek() ftell() fclose() It would seem useful to modify vorbisfile to abstract the functions used for reading, seeking, and closing a file. A seperate version of ov_open() could be available, which would take 3 extra arguments - to function pointers for these functions. We don't really need ftell() - it...

...t, myStreamPtr, bytes ); myStreamPtr += bytes; ..etc. etc. I didn't bother implementing a close function (I just stubbed it out). Looking at my read callback, I always seem to get requests for one object of varying size. I've modeled my callbacks on the stream IO CRTL stuff (fseek/fread/ftell/fclose), including parameters and return values. I assume this is correct? Any other obvious problems I should look for? Barring any epiphanies, I may end up having to implement a test version using ov_open to see if it's my callbacks (which I suspect). Thanks, Brian --- >8 ---- List a...

Hello, All. First, I want to thank Ian Malone and Ralph Giles, thanks for your kind replies. But I still have problems about seek. As you suggested, I could use ov_open_callbacks() to supply my own read/write/seek functions. So, can you give me an example? I?m sorry for my ignorance, because I haven?t used callbacks before. I analyzed the vorbisfile.c in Tremor, and I think I

This is an extended version of: https://www.redhat.com/archives/libguestfs/2019-September/msg00178.html It adds a couple of simple code changes, so it makes it possible to drop more modules. In addition, more unused modules were dropped. Pino Toscano (5): tests: switch away from xgetcwd daemon: move read_whole_file to common utils daemon: switch from read_file to read_whole_file daemon:
