\fB
.sp
int z_decomp_init  (void * \fIarg\fB, unsigned char * \fIoptions\fB, int \fIopt_len\fB, int \fIunit\fB, int \fIhdrlen\fB, int \fImru\fB, int \fIdebug\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIarg\fB\fR
pointer to the private state for the decompressor
.TP
\fB\fIoptions\fB\fR
pointer to the CCP option data describing the
compression that was negotiated with the peer
.TP
\fB\fIopt_len\fB\fR
length of the CCP option data at \fIoptions\fR
.TP
\fB\fIunit\fB\fR
PPP unit number for diagnostic messages
.TP
\fB\fIhdrlen\fB\fR
ignored (present for backwards compatibility)
.TP
\fB\fImru\fB\fR
maximum length of decompressed packets
.TP
\fB\fIdebug\fB\fR
debug flag; if non-zero, debug messages are printed.
.SH "DESCRIPTION"
.PP
The CCP options described by \fIoptions\fR must match the options
