\fBcc\fR [ \fIflag\fR ... ] \fIfile\fR ... \fB-lsip\fR [ \fIlibrary\fR ... ]
#include <sip.h>

\fBvoid\fR \fIsip_process_new_packet\fR(\fBsip_conn_object_t\fR \fIconn_object\fR,

.SH DESCRIPTION
.sp
.LP
The \fBsip_process_new_packet()\fR function receives incoming message, creates
a \fBSIP\fR message, processes it and passes it on to the application. For a
byte-stream protocol like \fBTCP\fR \fBsip_process_new_packet()\fR also takes
care of breaking the byte stream into message boundaries using the
\fBCONTENT-LENGTH\fR header in the \fBSIP\fR message. If the \fBSIP\fR message
arriving on \fBTCP\fR does not contain a \fBCONTENT-LENGTH\fR header, the
behavior is unspecified. \fBsip_process_new_packet()\fR deletes the \fBSIP\fR
message on return from the application's receive function, thus if the
application wishes to retain the \fBSIP\fR message for future use, it must use
\fBsip_hod_msg()\fR so that the message is not freed by
\fBsip_process_new_packet()\fR.
