.SH "DESCRIPTION"
.sp
The Network UPS Tools (NUT) \fBnutclient\fR library provides a number of useful functions for programs to use when communicating with \fBupsd\fR(8)\&. It provides high\-level representation of NUT data through client connection, devices, variables and commands\&. Unlike \fBupsclient\fR(3), all low\-level protocol details are hidden\&.
.sp
State is maintained across calls in an opaque structure called NUTCLIENT_t\&. Callers are expected to create one per client connection\&. These will be provided to most of the \fBnutclient\fR functions\&. The format of this structure is subject to change, and client programs must not reference elements within it directly\&.
.sp
NUTCLIENT_t represents the common connection information\&. Derived versions exist for each connection type (NUTCLIENT_TCP_t for TCP connection; actually the unique connection type, NUTCLIENT_TCP_t can be passed as NUTCLIENT_t parameter)\&.
.sp
See the nutclient\&.h header for more information\&.
.SH "ERROR HANDLING"
.sp
There is currently no specific mechanism around error handling\&.
