*result, unsigned int fieldnr)
Description

fonction pour obtenir la définition d'une colonne choisie
arbitrairement. La valeur de fieldnr doit
varier entre 0 et
mysql_num_fields(result)-1.
Valeur de retour
La structure MYSQL_FIELD pour la colonne
spécifiée.
Erreurs
Aucune.
Exemple
unsigned int num_fields;
unsigned int i;
MYSQL_FIELD *field;
num_fields = mysql_num_fields(result);
for(i = 0; i < num_fields; i++)
{
field = mysql_fetch_field_direct(result, i);
printf("La champ %u est %s\n", i, field->name);
