+
+.SH DESCRIPTION
+
+These calls are used to
+
+The \fBfqueue_create\fR() function creates an fqueue_t structure which
+is an event queue that stores events that occured within a certain
+\fBfset_t\fR.
+
+The \fBfqueue_destroy\fR() function frees any resources associated with
+an \fBfqueue_t\fR \fIfq\fR.
+
+The \fBfqueue_next\fR() function retrieves the next event (a \fIflow
+descriptor\fR) that is ready within the event queue \fIfq\fR.
+
+The \fBfevent\fR() function retrieves all events that occured on any
+\fIflow descriptor\fR within \fIset\fR and returns them in the event
+queue \fBfq\fR. If a \fBstruct timespec *\fI timeo\fR can be provided,
+it will return either with new events or when \fItimeo\fR has expired.
+If \fItimeo\fR is NULL, the call will block indefinitely until an
+event occurs.
+
+.SH RETURN VALUE
+
+On success, \fBfqueue_create\fR() returns a pointer to an
+\fBfqueue_t\fR.
+
+\fBfqueue_destroy\fR() has no return value.
+
+On success, \fBfevent\fR() returns the number of events that occured in \fIset\fR.
+
+.SH ERRORS
+
+\fBfqueue_create\fR() returns NULL when insufficient resources
+were available to create the \fBfqueue_t\fR.
+
+\fBfqueue_next\fR() and \fBfevent\fR() can return
+
+.B -EINVAL
+An invalid argument was passed (\fIfq\fR or \fIset\fR was \fINULL\fR).
+
+In addition, \fBfqueue_next\fR() can return

+.B -EPERM
+No more fds available in \fIfq\fR.

+Compile and link with \fI-louroboros\fR.
+
+.SH DESCRIPTION
+
+These calls are used to manage a set of \fIflow descriptors\fR.
+
+The \fBfset_create\fR() function creates and fset_t struct which holds
+a set of flow descriptors.
+
+The \fBfset_destroy\fR() function frees any resources associated with
+an \fBfset_t \fIset\fR.
+
+The \fBset_zero\fR() function removes all flow descriptors from an
+\fBfset_t \fIset\fR.
+
+The \fBset_add\fR() function adds a flow descriptor \fIfd\fR to the
+\fBfset_t \fIset\fR. A flow descriptor can be in at most one fset at a
+time.
+
+The \fBfset_del\fR() function removes a flow descriptor \fIfd\fR from
+the \fBfset_t \fIset\fR. \fBfset_del\fR() ignores invalid input.
+
+The \fBfset_has\fR() function checks whether a flow descriptor \fIfd\fR is
+an element of the \fBfset_t \fIset\fR.
+
+.SH RETURN VALUE
+
+On success, \fBfset_create\fR() returns a pointer to an \fBfset_t\fB.
+
+\fBfset_destroy\fR(), \fBset_zero\fR() and \fBfset_del\fR() have no return value.
+
+\fBfset_add\fR() returns 0 on success or an error code.
+
+\fBfset_has\fR() returns true when \fIfd\fR is in the set, false if it
+is not or on invalid input.
+
+.SH ERRORS
+
+\fBfset_create\fR() returns NULL when insufficient resources
+were available to create the \fBfset_t\fR.
+
+\fBfset_add\fR() can return the following errors:
+
+.B -EINVAL
+An invalid argument was passed (\fIset\fR was NULL or \fIfd\fR was
+invalid).
+
+.B -EPERM
+The passed flow descriptor \fIfd\fR was already in another \fBfset_t\fR.
+
