◆ check_acl()

bool check_acl ( struct Mailbox m,
AclFlags  acl,
const char *  msg 
)

Check the ACLs for a function.

Parameters
mMailbox
aclACL, see AclFlags
msgError message for failure
Return values

◆ collapse_all()

void collapse_all ( struct MailboxView mv,
struct Menu menu,
int  toggle 
)

Collapse/uncollapse all threads.

Parameters
mvMailbox View
menucurrent menu
toggletoggle collapsed state

This function is called by the OP_MAIN_COLLAPSE_ALL command and on folder enter if the $collapse_all option is set. In the first case, the toggle parameter is 1 to actually toggle collapsed/uncollapsed state on all threads. In the second case, the toggle parameter is 0, actually turning this function into a one-way collapse.
