|
|
* O_RDONLY - opens the file for read access.
|
|
* O_WRONLY - opens the file for write access.
|
|
* O_RDWR - opens the file for both reading and writing.
|
|
* O_CREAT - creates the file, if it doesn't already exist.
|
|
* O_EXCL - if both O_CREAT and O_EXCL are set and the file already exists, dio_open() will fail.
|
|
* O_TRUNC - if the file exists and is opened for write access, the file will be truncated to zero length.
|
|
* O_APPEND - write operations write data at the end of the file.
|
|
* O_NONBLOCK - sets non blocking mode.
|
|
* O_NOCTTY - prevent the OS from assigning the opened file as the process's controlling terminal when opening a TTY device file.
|
|
* F_SETLK - Lock is set or cleared. If the lockis held by someone else dio_fcntl() returns-1.
|
|
* F_SETLKW - like F_SETLK,but in case the lock is held by someone else, dio_fcntl() waits until the lock is released.
|
|
* F_GETLK - dio_fcntl() returns an associative array (as described below) if someone elseprevents lock. If there is no obstruction key "type" will setto F_UNLCK.
|
|
* F_DUPFD - finds the lowest numbered availablefile descriptor greater than or equal to argsand returns them.
|
|
* F_SETFL - Sets the file descriptors flags tothe value specified by args, which can be O_APPEND, O_NONBLOCK or O_ASYNC. To use O_ASYNC you will need to use the PCNTL extension.
