Part of NOMP project
|
|
Simple lightweight & fast - a more efficient block notify script in pure C.
|
|
|
|
(may also work as coin switch)
|
|
|
|
Platforms : Linux, BSD, Solaris (mostly OS independent)
|
|
|
|
Build with:
|
|
gcc blocknotify.c -o blocknotify
|
|
|
|
|
|
Example usage in daemon coin.conf using default NOMP CLI port of 17117
|
|
blocknotify="/bin/blocknotify 127.0.0.1:17117 dogecoin %s"
