int upscli_fd(UPSCONN_t *ups);

DESCRIPTION
|
|
-----------
|
|
|
|
The *upscli_fd()* function takes the pointer 'ups' to a `UPSCONN_t`

state structure and returns the value of the file descriptor for
|
|
that connection, if any.
|
|
|
|
This may be useful for determining if the connection to linkman:upsd[8]
|
|
has been lost.
|
|
|
|
RETURN VALUE

------------
|
|
|
|
The *upscli_fd()* function returns the file descriptor, which
|
|
may be any non-negative number.
|
|
|
|
It returns -1 if an error occurs.
