- /** 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.
