yesterday i wrote one routine, so you can examine that:

Here is a rewrite that eliminates the gotos and the "silly" macros. There
is no guarantee that it (or the original code) is correct. Some people
have a twisted panties problem with do/while blocks. In this case they are
easily recoded and I leave the joy of doing so to anyone who might care.

int getStdI(char* tmp, int sztmp)
{
int i, r, c;
char *a;

if(tmp==0||sztmp<=1) return 0;
*tmp=0; c=0;

do {
Fflush_m(stdout_m);
i=fgets_m(tmp, sztmp, stdin_m); /* i=strlen(tmp) */
if((i<=0) || (i+1==sztmp)) { /* errore di input */
if(++c>=3) return 0;
P("Stringa Troppo lunga o Errore hardware\nreturneinserire > ");
Fflush_m(stdin_m);
continue;
}
} while(0);

a=tmp+i; r=i;
do {
if(a<=tmp) break;
--a;
if (!((*a==10)||(*a==13)||(Isspace_m(*a))) break;
*a=0; --r;
} while(1);
return r;
}

I stand in the footprints of giants.
