file descriptors การใช้

• File descriptors are also reference counted under Unix-like systems.
• File descriptors did not need to be embedded in the executable code.
• Application software opens a CAN device descriptor and gets back a file descriptor.
• The file descriptor table in Unix is an example of a C-list.
• Consequently it doesn't really matter what file the file descriptors point at.
• File descriptor leaks are another common vector.
• Moreover the child inherits the file descriptors of the parent, and any mmaped memory blocks.
• The class is a file descriptor that represents a source or sink ( destination ) of bytes.
• That is, a stream that presents a normal file descriptor interface but reads from a string.
• But file descriptors are also created for things like anonymous pipes and network sockets via different methods.
• It uses 64 bit file descriptors ( supports files or devices up to 2 64 bytes ).
• Since this impossibility result, libraries for tracking file descriptors and ensuring correctness have been proposed by researchers.
• The sets of file descriptor used in select are finite in size, depending on the operating system.
• In these DRI3 operations GEM buffer objects are passed as DMA-BUF file descriptors instead of GEM names.
• The kernel provides these and other basic services : scheduling, timer and clock handling, file descriptor management.
• CodeAnalyst also uses other open-source components, including the libelf, and the Binary File Descriptor library.
• The only default file descriptors ( fd for short ) on Unix are stdin, stdout, and stderr.
• Each Unix daemon ) should expect to have three standard POSIX file descriptors, corresponding to the three standard streams:
• In Unix-like systems, file descriptors can refer to any Unix file type named in a file system.
• And properly handing how fork ( ) works ( particularly in respect of file descriptors ) can require labour too.
