2010-05-17Add reset_schedlock declaration in target.h.Joel Brobecker1-2/+3
This patches improves a couple of previous patches: - one that introduces reset_schedlock, but failed to add a declarationl; - one that was checked in to avoid a compilation failure due to that missing declaration. It also improves the declaration itself to better conform to our coding practices. Same for the comments. 2010-05-17 Joel Brobecker <brobecker@adacore.com> * target.h (reset_schedlock): Add declaration. * infrun.c (reset_schedlock): Add missing void in function profile. * target.c (target_mourn_inferior): Delete local declaration of reset_schedlock.
