#include
#include
#include
#include

int main( argc, argv )
int argc;
char** argv;
{

struct pst_status buf;
size_t psize;
size_t count;
int index;

index = getppid();
psize = sizeof( struct pst_status );
count = 0;

if ( pstat_getproc( &buf, psize, 0, index ) < 0 ) {

perror( "pstat_getproc" );
return -1;

}

printf( " Information %s\n", buf.u_comm);

return 0;

Looks like you mislabeled you name
buf.u_comm should be buf.pst_ucomm

I made a few changes but not many, I was able to compile and run the following:

#include
#include
#include
#include

main(argc, argv)
int argc ;
char **argv ;
{

struct pst_status buf;

size_t psize;
size_t count;
int index;

index= (int) getppid();
count=0;
if (pstat_getproc(&buf,sizeof(buf), (size_t)0,index) != -1)
{
(void) printf("Information Process id: %d Program Name: %s\n", index, buf.pst_ucomm);
}
else {
(void) perror("pstat_getpoc");
return -1;
}

return(0) ;
}
