path_open()

Open file located at the given path Inputs:

• Fd dirfd The fd corresponding to the directory that the file is in
• LookupFlags dirflags Flags specifying how the path will be resolved
• char *path The path of the file or directory to open
• u32 path_len The length of the path string
• Oflags o_flags How the file will be opened
• Rights fs_rights_base The rights of the created file descriptor
• Rights fs_rightsinheriting The rights of file descriptors derived from the created file descriptor
• Fdflags fs_flags The flags of the file descriptor Output:
• Fd* fd The new file descriptor Possible Errors:
• Errno::Access, Errno::Badf, Errno::Fault, Errno::Fbig?, Errno::Inval, Errno::Io, Errno::Loop, Errno::Mfile, Errno::Nametoolong?, Errno::Nfile, Errno::Noent, Errno::Notdir, Errno::Rofs, and Errno::Notcapable
