ldr:shel
This is "nn::ldr::detail::IShellInterface".
Cmd | Name |
---|---|
0 | #SetProgramArgument |
1 | #FlushArguments |
SetProgramArgument
Takes a type-0x9 input buffer with launch arguments (as string), an u32 (size of arguments string), and an input title-id.
Loads a process for the specified title-id and passes along the supplied arguments. Loaded processes are kept in a queue waiting for PM to launch them. The maximum number of waiting processes in this list is 10.
FlushArguments
Clears the loaded processes waiting queue.
ldr:dmnt
This is "nn::ldr::detail::IDebugMonitorInterface".
Cmd | Name |
---|---|
0 | #SetProgramArgument |
1 | #FlushArguments |
2 | #GetProcessModuleInfo |
GetProcessModuleInfo
Takes in a u64 Process ID, and a C descriptor out array of #ModuleInfos. Returns the number of ModuleInfos copied to output.
ldr:pm
This is "nn::ldr::detail::IProcessManagerInterface".
Cmd | Name |
---|---|
0 | CreateProcess |
1 | #GetProgramInfo |
2 | #PinProgram |
3 | #UnpinProgram |
GetProgramInfo
Takes an ncm::ProgramLocation, parses the NPDM, and writes a #ProgramInfo to a C descriptor buffer.
PinProgram
Takes an ncm::ProgramLocation, returns a u64 "PinId".
UnpinProgram
Takes a PinId from #PinProgram.
