dio_open -- Opens a new filename with specified permissions of flags and creation
permissions of mode
Description
resource dio_open (string filename, int flags [, int mode])
dio_open() opens a file and returns a new file descriptor for it, or -1 if any
error occurred. If flags is O_CREAT, optional third parameter mode
will set the mode of the file (creation permissions). The flags parameter can be
one of the following options:
-
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
The flags parameter can also include any combination of the following flags:
-
O_CREAT - creates the file, if it doesn't already exist
-
O_EXCL - if both, O_CREAT and O_EXCL are set, dio_open() fails, if file already
exists
-
O_TRUNC - if file exists, and its opened for write access, file will be truncated to zero
length.
-
O_APPEND - write operations write data at the end of file
-
O_NONBLOCK - sets non blocking mode
