Functions Omitted
mode_t umask( mode_t cmask ); int mkfifo( const char *path, mode_t mode ); int chmod( const char *path, mode_t mode ); // TBA int fchmod( int fd, mode_t mode ); // TBA int chown( const char *path, uid_t owner, gid_t group ); int utime( const char *path, const struct utimbuf *times ); // TBA int ftruncate( int fd, off_t length ); // TBA |
Notes
-
If a call to open() or creat() supplies the third _mode_ parameter, it will currently be ignored.
-
Most of the functionality of these functions depends on the underlying filesystem.
-
Currently access() only checks the F_OK mode explicitly, the others are all assumed to be true by default.
-
The maximum number of open files allowed is supplied by the CYGNUM_FILEIO_NFILE option. The maximum number of file descriptors is supplied by the CYGNUM_FILEIO_NFD option.
