/** The open() function establishes the connection between a file and a file
|
|
descriptor. It creates an open file description that refers to a file
|
|
and a file descriptor that refers to that open file description. The file
|
|
descriptor is used by other I/O functions to refer to that file.
|
|
|
|
The open() function returns a file descriptor for the named file that is
|
|
the lowest file descriptor not currently open for that process. The open
|
|
file description is new, and therefore the file descriptor shall not
|
|
share it with any other process in the system.
|
|
|
|
The file offset used to mark the current position within the file is set
|
|
to the beginning of the file.
|
|
|
|
The file status flags and file access modes of the open file description
|
|
are set according to the value of oflags.
|
|
|
|
Values for oflags are constructed by a bitwise-inclusive OR of flags from
|
|
the following list, defined in <fcntl.h>. Applications shall specify
|
|
exactly one of { O_RDONLY, O_RDWR, O_WRONLY } in the value of oflags.
|
|
Any combination of { O_NONBLOCK, O_APPEND, O_CREAT, O_TRUNC, O_EXCL } may
|
|
also be specified in oflags.
|
|
|
|
Values for mode specify the access permissions for newly created files.
|
|
|
|
@param[in] Path The path argument points to a pathname naming the
|
|
object to be opened.
|
|
@param[in] oflags File status flags and file access modes of the
|
|
open file description.
|
|
@param[in] mode File access permission bits as defined in
|
|
<sys/stat.h>.
|
|
|
|
@return Upon successful completion, open() opens the file and returns
|
|
a non-negative integer representing the lowest numbered
|
|
unused file descriptor. Otherwise, open returns -1 and sets
|
|
errno to indicate the error. If a negative value is
|
|
returned, no files are created or modified.
|
|
|
|
@retval EMFILE No file descriptors available -- Max number already open.
|
|
@retval EINVAL Bad value specified for oflags or mode.
|
|
@retval ENOMEM Failure allocating memory for internal buffers.
|
|
@retval EEXIST File exists and open attempted with (O_EXCL | O_CREAT) set.
|
|
@retval EIO UEFI failure. Check value in EFIerrno.
