The

function is equivalent to the
.Fn flopen
function except in the case where the
.Fa path
specifies a relative path.
In this case the file to be opened is determined relative to the directory
associated with the file descriptor
.Fa fd
instead of the current working directory.
If
.Fn flopenat
is passed the special value
.Dv AT_FDCWD
in the

parameter, the current working directory is used
and the behavior is identical to a call to
.Fn flopen .
