Function ACLGetUserCommandBit

src/acl.cpp:388–392

Check if the specified command bit is set for the specified user. * The function returns 1 is the bit is set or 0 if it is not. * Note that this function does not check the ALLCOMMANDS flag of the user * but just the lowlevel bitmask. * * If the bit overflows the user internal representation, zero is returned * in order to disallow the execution of the command in such edge case. */

 * If the bit overflows the user internal representation, zero is returned
 * in order to disallow the execution of the command in such edge case. */

/* When +@all or allcommands is given, we set a reserved bit as well that we
