typedef struct {
char * hostname;
int sysnr;
char * gateway_host;
char * gateway_service;
} RFC_CONNOPT_R3ONLY;
This structure is defined in SAPRFC.H.
· hostname
host name of target system
Host names can be regular host names defined in a ‘hosts’ file, an IP address like 123.123.123.123 or a saprouter address as /H/hostname/S/port/H/host/S/port/...
· sysnr
system number (0-99)
This is the number by which the target system is identified. In general, this is 0.
· gateway_host
gateway hostname
If the pointer is NULL, the gateway is assumed to run at ‘hostname’.
· gateway_service
gateway service
If the pointer is NULL, the service “sapgw##” with ## = ‘sysnr’ is assumed.
