So there is one errno for each thread. Linux Errno Example Macro: int EINVAL Invalid argument. A given error code may mean different things on different operating systems. This happens not only when you use link (see Hard Links) but also when you rename a file with rename (see Renaming Files).

Macro: int EFBIG File too big; the size of a file would be larger than allowed by the system. Errno.h Windows The author of this document will not do fixups on the scripting examples to conform to the changing standard. For example, "Error no is : 17", which doesn't really say much. In next execution, it throws an error number 17, which is "File already exist".

This error never occurs on GNU/Hurd systems.

Macro: int EMFILE The current process has too many files open and can’t open any more.

Einval Errno The technique of spawning child processes is used to delegate some work to a child process when there is no reason to stop the execution of the parent.

When you are running some program on Linux environment, you might notice that it gives some error number. See Also For more information, please refer to the MySQL Reference Manual, which may already be installed locally and which is also available online at http://dev.mysql.com/doc/. When computer programs are executed, the operating system creates an abstract entity called a process in which the book-keeping for that program is maintained. http://softacoustik.com/error-codes/linux-system-error-codes.php Do we need to unmount the SD/MMC cards?
