We no longer add these. If you use Emacs, configure it yourself.
Also, due to our "smart-tab" usage the editor anyway does a subpar
job handling our tabs. However, on the upside every user can choose
whatever tab-width he/she prefers. If "smart-tabs" are used properly
(like we do), every tab-width will work.
No manual changes, just ran commands:
F=($(git grep -l -e '-\*-'))
sed '1 { /\/\* *-\*- *[mM]ode.*\*\/$/d }' -i "${F[@]}"
sed '1,4 { /^\(#\|--\|dnl\) *-\*- [mM]ode/d }' -i "${F[@]}"
Check remaining lines with:
git grep -e '-\*-'
The ultimate purpose of this is to cleanup our files and eventually use
SPDX license identifiers. For that, first get rid of the boilerplate lines.

/**
|
|
* NmtSyncOp:
|
|
*
|
|
* A helper object used when synchronously waiting for an asynchronous
|
|
* operation to complete.
|
|
*
|
|
* The caller first does:
|
|
*
|
|
* |[
|
|
* NmtSyncOp op;
|
|
*
|
|
* nmt_sync_op_init (&op);
|
|
* ]|
|
|
*
|
|
* It then passes the op as the user_data to the async operation's
|
|
* callback function, and then calls nmt_sync_op_wait_boolean() or
|
|
* nmt_sync_op_wait_pointer() to wait for the result.
|
|
*
|
|
* When the async callback is invoked, it should call
|
|
* nmt_sync_op_complete_boolean() or nmt_sync_op_complete_pointer() to
|
|
* return a result or an error to the caller.
|
|
*
|
|
* There is no free/clear function; any memory that needs to be freed
|
|
* will have been returned to the caller from
|
|
* nmt_sync_op_wait_boolean() or nmt_sync_op_wait_pointer(), so there
|
|
* is nothing left that needs to be freed.
