NAME

isdn_pspdn_call, isdn_pspdn_disc, isdn_pspdn_stat, isdn_pspdn_noinfo − support IP connection via X.25 packet switched network

SYNOPSIS

#include <newsisdn/isdn_iotype.h>
 intisdn_pspdn_stat(ch, info)
intch;
structc_status ∗info;

intisdn_pspdn_noinfo(ch, noinfo)
intch;
structn_info∗noinfo;

intisdn_pspdn_call(addr, flag, ud, wait_time)
char∗addr;
intflag;
char∗ud;
intwait_time;

intisdn_pspdn_disc(ch, wait_time)
intch;
intwait_time;

DESCRIPTION

isdn_pspdn_stat copies the X.25 connection status of channel ch into the info structure

isdn_pspdn_noinfo copies the peer X.25 address of channel ch into the noinfo structure.  However, this information is only valid when isdn_pspdn_stat() returns status of CALL_SETUP, CALL_ALERT or CALL_EST. 

isdn_pspdn_call makes an IP connection to the specified peer addr.  This function waits in max wait_time seconds for the connection to establish.  It returns immediately if wait_time is set to 0.  Currently, flag and ud are reserved (not supported yet); flag should be 0 and ud should be (char ∗)0.  On success, isdn_pspdn_call returns an positive value ch to be used as channel identification. 

isdn_pspdn_disc closes the IP connection on ch channel.  The function waits in max wait_time seconds for disconnection.  It returns immediately if wait_time is set to 0. 

RETURN VALUE

Above functions except isdn_pspdn_call return 0 on success.  In case of execution error, a −1 is returned with an error code stored in errno.  On timeout a −2 is returned.  In case of failure to establish or deestablish a call, a −3 is returned; the cause value can be interrogated with isdn_pspdn_stat.
