.SH "DESCRIPTION"
.sp
The \fBnutclient_destroy()\fR function destroys a \fINUTCLIENT_t\fR or derived (like \fINUTCLIENT_TCP_t\fR) connection object, and frees allocated memory\&.
.sp
The \fBstrarr\fR type represents an array of C strings (array of char pointer)\&. The array must always be terminated by a NULL pointer\&. Pointed strings must be allocated by (x)calloc or (x)strdup\&.
.sp
The \fBstrarr_alloc()\fR function allocates a \fIstrarr\fR array with the specified number of (non\-initialized) string pointers\&. Another additional pointer set to 0 is added at the end of the array\&.
.sp
The \fBstrarr_free\fR function frees a \fIstrarr\fR array\&. It also frees all pointed strings\&.
.sp
\fIdev\fR is the device name\&.
