It's realy works?
If I understand, I can do this:
int (*custom_function)(void*, const char*, int);
if ((custom_function =
dbi_driver_specific_function(dbi_conn_get_driver(mdb->db),
"PQputCopyData")) != NULL) {
do {
res = custom_function(myconn->connection, (const char
*)mdb->cmd, (int)len);
} while (res == 0 && --count > 0);
But have an error like:
dbi.c:863: error: invalid conversion from 'void*' to 'int (*)(void*,
const char*, int)'
If I try:
if ((custom_function =
(*custom_function)(dbi_driver_specific_function(dbi_conn_get_driver(mdb->db),
"PQputCopyData"))) != NULL) {
do {
res = custom_function(myconn->connection, (const char
*)mdb->cmd, (int)len);
} while (res == 0 && --count > 0);
dbi.c:863: error: too few arguments to function
It's possible?
Thanks
