[C] struct, vettore di struct errore

[Sirbako]

questa è la parte del codice:

typedef struct
{
char cmd[100];
int pid;
} t_figlio;

#define MAX_FIGLI 100

t_figlio figli[MAX_FIGLI];
int tot=0;

void update_figli(int pid,char * arg){
int i=0;
while(i<MAX_FIGLI && figli[i]!=pid) i++;
strcpy(figli[i].cmd,arg);
}

void init_figli(){
int i;
for(i=0;i<MAX_FIGLI;i++)
figli[i].pid=0;

}
void add_figlio(int pid){
int i;
i=0;
while(i<MAX_FIGLI && figli[i]!=0) i++;
figli[i].pid=pid;
tot=i;
}

void rem_figlio(int pid){

int i,k;
i=0;
while(i<MAX_FIGLI && figli[i]!=pid) i++;
if (i==tot) exit(-1);
for(k=i;k<tot;k++) {
figli[k].pid=figli[k+1].pid;
strcpy(figli[k].cmd,figli[k].cmd)
}
tot--;

}

ora, quando compilo dice:

che diavolo vuole?

Ho preso il tuo codice pari pari, gli ho solo messo all'inizio 2 include (<string.h> e <stdlib.h>) e poi ho compilato con:
gcc -Wall -c -o prova.o prova.c
Risultato:
prova.c: In function `update_figli':
prova.c:17: invalid operands to binary !=
prova.c: In function `add_figlio':
prova.c:30: invalid operands to binary !=
prova.c: In function `rem_figlio':
prova.c:39: invalid operands to binary !=
prova.c:44: syntax error before '}' token
Correzioni:
void update_figli(int pid,char * arg){
int i=0;
while(i<MAX_FIGLI && figli[i].pid!=pid) i++;
strcpy(figli[i].cmd,arg);
}void add_figlio(int pid){
int i;
i=0;
while(i<MAX_FIGLI && figli[i].pid!=0) i++;
figli[i].pid=pid;
tot=i;
}void rem_figlio(int pid){

int i,k;
i=0;
while(i<MAX_FIGLI && figli[i].pid!=pid) i++;
if (i==tot) exit(-1);
for(k=i;k<tot;k++) {
figli[k].pid=figli[k+1].pid;
strcpy(figli[k].cmd,figli[k].cmd);
}
tot--;
