/** 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.
