+UPSCLI_UPSERROR(3)
+==================
+
+NAME
+----
+
+upscli_upserror - Get current error number for connection
+
+SYNOPSIS
+--------
+
+ #include <upsclient.h>
+
+ int upscli_upserror(UPSCONN_t *ups);
+
+DESCRIPTION
+-----------
+
+The *upscli_upserror*() function takes the pointer 'ups' to a
+`UPSCONN_t` state structure and returns the value of the internal error
+number, if any. 
+
+This is typically used to check for certain error values like
+`UPSCLI_ERR_UNKCOMMAND`.  That specific error can be used for detecting
+older versions of linkman:upsd[8] which might not support a given command.
+
+Some error messages have additional meanings, so you should use
+linkman:upscli_strerror[3] to obtain readable error messages.
+
+RETURN VALUE
+------------
+
+The *upscli_upserror*() function returns one of the `UPSCLI_ERR_*`
+values from `upsclient.h`, or 0 if no error has occurred.
