.SH "NAME"
|
|
upscli_connect \- Open a connection to a NUT upsd
|
|
.SH "SYNOPSIS"
|
|
.sp
|
|
.nf
|
|
#include <upsclient\&.h>
|
|
.fi
|
|
.sp
|
|
.nf
|
|
int upscli_connect(UPSCONN_t *ups, const char *host, int port, int flags);
|
|
.fi
|
|
.SH "DESCRIPTION"
|
|
.sp
|
|
The \fBupscli_connect()\fR function takes the pointer \fIups\fR to a UPSCONN_t state structure and opens a TCP connection to the \fIhost\fR on the given \fIport\fR\&.
|
|
.sp
|
|
\fIflags\fR may be either UPSCLI_CONN_TRYSSL to try a SSL connection, or UPSCLI_CONN_REQSSL to require a SSL connection\&.
|
|
.sp
|
|
If SSL mode is required, this function will only return successfully if it is able to establish a SSL connection with the server\&. Possible reasons for failure include no SSL support on the server, and if \fBupsclient\fR itself hasn\(cqt been compiled with SSL support\&.
|
|
.sp
|
|
You must call \fBupscli_disconnect\fR(3) when finished with a connection, or your program will slowly leak memory and file descriptors\&.
|
|
.SH "RETURN VALUE"
|
|
.sp
|
|
The \fBupscli_connect()\fR function modifies the UPSCONN_t structure and returns 0 on success, or \-1 if an error occurs\&.
|
|
.SH "SEE ALSO"
|
|
.sp
|
|
\fBupscli_disconnect\fR(3), \fBupscli_fd\fR(3), \fBupscli_splitaddr\fR(3), \fBupscli_splitname\fR(3), \fBupscli_ssl\fR(3), \fBupscli_strerror\fR(3), \fBupscli_upserror\fR(3)
