EINVAL fd was created via a call to timerfd_create(2) and the wrong size buffer was given to read(); see timerfd_create(2) for further information. Manual pages are a descriptive help system that sometimes contains procedural help ("How do I..?") and sometimes the reason the command itself was created (the goal of the program). Most commands have simple uses and you can easily understand how they function. There is usually help available from the commands themselves by executing the command with the "--help" option. this contact form

POSIX.1-2001 allows either error to be returned for this case, and does not require these constants to have the same value, so a portable application should check for both possibilities.

Remember, manual pages are not designed to be a help system, but they do provide descriptions of the commands themselves. Is fgets a shell command? Is fgets a shell command? A testament to simplicy and usability, tens of thousands of pages of documenation exist, viewable in a common file format, usable via command line, or easily printed with minimal effort.

EAGAIN or EWOULDBLOCK The file descriptor fd refers to a socket and has been marked nonblocking (O_NONBLOCK), and the read would block. What versions? Don't worry too much about it right now. Another weird thing is that having the same man page installed in another linux box, in the same location, is opened without any problem (typing man nfwatchdog from any location).

Melson Nothing is more terrible than Rio Grande MicroSolutions ignorance in action.

Currently, only some file systems (among them: Btrfs, ext2, ext3, and ext4) have full support for returning the file type in d_type. Manual pages were generally written by the person(s) that wrote the program themselves - they are descriptive enough to be of assistance, but not intended to be full documentation. I have created a man page, named nfwatchdog.1.gz.

EFAULT buf is outside your accessible address space. The "FSF" indicates this was written by the Free Software Foundation, Inc. (FSF). Although it might be beyond your comfort level now, if you acquire the source code to programs you can frequently find similar information in the READMEs that accompany the programs. On error, it returns a positive error number (listed under ERRORS).

The pipe is also used to indicate options that equate to each other. On some systems, such as a dedicated server, you may not have a GUI installed at all. They are a reference that frequently explains how the command functions so that you can easily understand its use. OPTIONs are preceeded by hyphens, and you can either specify them individually if you leave a space inbetween ( ls -a -l /home) or altogether ( ls -al /home ) if
