From e27ae046960e20144892cf8252d8a672a48b0123 Mon Sep 17 00:00:00 2001 From: Subv Date: Sun, 24 Sep 2017 19:09:13 -0500 Subject: HLE/APT: Always set up the APT parameter when starting a library applet. Only use the HLE interface if an HLE applet with the desired id was started. This commit reorganizes the APT code surrounding parameter creation and delivery to make it easier to support LLE applets in the future. As future work, the HLE applet interface can be reworked to utilize the same facilities as the LLE interface. --- src/core/hle/service/apt/apt.cpp | 73 +++++++++++++++++++++++++--------------- 1 file changed, 45 insertions(+), 28 deletions(-) (limited to 'src/core/hle/service/apt/apt.cpp') diff --git a/src/core/hle/service/apt/apt.cpp b/src/core/hle/service/apt/apt.cpp index 8c0ba73f2..c36775473 100644 --- a/src/core/hle/service/apt/apt.cpp +++ b/src/core/hle/service/apt/apt.cpp @@ -165,7 +165,11 @@ void SendParameter(const MessageParameter& parameter) { next_parameter = parameter;
