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