rapi_strerror(3) Library Functions Manual rapi_strerror(3)NAME
rapi_strerror - Get a RAPI error message string
LIBRARY
RAPI Library (librsvp.so, librsvp.a)
SYNOPSIS
#include <rapi.h>
const char *rapi_strerror( int ErrorCode, int ErrorValue);
PARAMETERS
Specifies the RAPI error code that was returned by a failed call to a RAPI routine. Specifies the RAPI error value that was returned by a
failed call to a RAPI routine.
DESCRIPTION
The rapi_strerror() routine maps an error code and value to an error message string, and returns a pointer to that error message string.
RETURN VALUES
Upon successful completion, the rapi_strerror() routine returns a pointer to an error message string. If the arguments are out of bounds,
the routine returns NULL.

rapi_sender(3) Library Functions Manual rapi_sender(3)NAME
rapi_sender - Specify Resource ReSerVation Protocol (RSVP) API sender parameters
LIBRARY
RAPI Library (librsvp.so, librsvp.a)
SYNOPSIS
#include <rapi.h>
int rapi_sender( rapi_sid_t Sid, unsigned int flags, rapi_addr_t *Lhost, rapi_filter_t *SenderTemplate,
rapi_tspec_t *SenderTspec, rapi_adspec_t *SenderAdspec, rapi_policy_t *SenderPolicy, int TTL);
PARAMETERS
Specifies the session handle that was returned by a successful call to the rapi_session routine. Unused. Points to a rapi_addr_t struc-
ture that contains the source IP address and the UDP source port from which data will be sent, or is NULL. This is an optional parameter.
If the source IP address is INADDR_ANY, the API uses the default IP address of the local host. This is sufficient unless the host
is multi-homed. The port number might be zero if the protocol for the session does not have any ports.
If the Lhost parameter is NULL, the application indicates that it is withdrawing its registration as a sender. All the following
parameters are ignored. Points to a RSVP API (RAPI) filter specification structure that specifies the format of data packets to be
sent, or is NULL. This is an optional parameter. See RSVP(7) for a description of RAPI objects and formats.
If the SenderTemplate parameter is NULL, RAPI creates a sender template from the Dest and Lhost parameters. The Dest parameter was
supplied in a previous rapi_session() call. If parameter is not NULL, the Lhost parameter is ignored.
This parameter is required in order to declare the sender template for a session using IP Security (IPSEC). An IPSEC session is
created with the RAPI_GPI_SESSION bit set. Points to a Tspec that defines the traffic that this sender will create. Points to a
RAPI Adspec structure, or is NULL. See RSVP(7) for a description of RAPI objects and formats. Points to a sender policy structure,
or is NULL. Specifies the IP Time-to-Live (TTL) value with which multicast data is sent. This allows RSVP to send its control mes-
sages with the same TTL scope as the data packets.
DESCRIPTION
The rapi_sender() routine defines, redefines, or deletes the parameters for a flow of data it intends to send and for which receivers can
make reservations. An application can call this routine more than once for the same API session, with the most recent call taking prece-
dence.
If the call to rapi_sender() succeeds, the application might receive upcalls of type RAPI_RESV_EVENT or RAPI_PATH_ERROR.
RETURN VALUES
Upon successful completion, the rapi_sender() routine returns zero (0). If there is a synchronous error, the routine returns a RAPI error
code.
