dio_open
(PHP 4 >= 4.2.0)
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 FALSE if any error occurred. If flags is O_CREAT,
the 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 the file already exists.
O_TRUNC - if the file exists, and its 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.
