If I get it declared static the compiler say the next:
/home/Programas/preguntas/src/bd.cpp: At global scope:
/home/Programas/preguntas/src/bd.cpp:168: error: cannot declare member
function `static int bd::analisis_ultimo(void*, int, char**, char**)' to have
static linkage
here is part of the code:
ultima_entrada * bd::cargar_ultimo_uso()
{
string cola = "SELECT * FROM ultimo;";
char *zErrMsg;
int ret = sqlite3_exec( base_datos, cola.c_str(), (bd::analisis_ultimo), 0,
&zErrMsg );
if( ret != SQLITE_OK )
{
cout<<"Error al ejecutar la consulta SQL:"<<cola<<endl;
cout<<"Numero de error:"<<ret<<endl;
cout<<"Descripcion del error:"<<zErrMsg<<endl;
}
else
{
return( ultima );
}
}
static int bd::analisis_ultimo( void *NotUsed, int argc, char **argv, char
**azColName )
{
int i;
for(i=0; i<argc; i++){
printf("%s = %s\n", azColName[i], argv[i] ? argv[i] : "NULL");
}
printf("\n");
return 0;
}
