Hi,

I juste compiled a sample program, used to monitor network throughpout
with function from libperfstat.a.

The problem is that the program dumps a core when it tries to execute
this call:
ret = perfstat_netinterface((perfstat_id_t *)FIRST_NETINTERFACE, stat,
sizeof(perfstat_netinterface_t),tot);
I tried on an AIX 5.3, ML04.

The program and source are from:
http://www-941.ibm.com/collaboration.../WikiPtype/ryo

If I download the "net" binary, it works like a charm.

I'm wondering... can someone with AIX 5.3 ML03 send me the
/usr/lib/libperfstat.a ? I'm pretty sure that it'd do the trick ;-)

Cheers,
Valoche

HERE IS THE CODE: compile with cc net.c -o net -lperfstat

#include

#ifndef FIRST_NETINTERFACE
#define FIRST_NETINTERFACE ""
#endif
int main(int argc, char* argv[]) {
int i, ret, tot;
perfstat_netinterface_t *stat;

tot = perfstat_netinterface(NULL, NULL,
sizeof(perfstat_netinterface_t), 0);
stat = malloc(sizeof(perfstat_netinterface_t)*tot);

ret = perfstat_netinterface((perfstat_id_t
*)FIRST_NETINTERFACE, stat, sizeof(perfstat_netinterface_t),tot);
while(1) {
ret = perfstat_netinterface((perfstat_id_t *)"", stat,
sizeof(perfstat_netinterface_t),tot);
if(ret <= 0) {
printf("tot=%d ret=%d errno=%d\n",tot,ret,errno);
perror("x");
exit(42);
}

for (i = 0; i < ret; i++) {
printf("\nStatistics for networks : %s\n",
stat[i].name);
printf("----------------------\n");
