== ldr: | == SetProgramArgument == | ||
Takes a type-0x9 input buffer with launch arguments (as string), an u32 (size of arguments string), and an input [[NCM_services#ProgramId|ProgramId]]. No output. | |||
[11.0.0+] Now takes a type-0x5 buffer instead of type-0x9. Now takes a total of 8-bytes of input, instead of 0x10-bytes total. | |||
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 == | |||
No input/output. | |||
Clears the loaded processes waiting queue. | |||

Takes a type-0xA output buffer of [[#ModuleInfo]] and an input u64 ProcessId. Returns an output s32. | |||

Takes an input [[#PinId]], an input [[#CreateProcessFlag]] and an input ResourceLimit handle. Returns an output Process handle. | |||
== GetProgramInfo == | |||
Takes a type-0x1A output buffer containing a [[#ProgramInfo]] and a [[NCM_services#ProgramLocation|ProgramLocation]]. No output. | |||
[20.0.0+] Now takes an additional input u16. | |||
== PinProgram == | |||
Takes a [[NCM_services#ProgramLocation|ProgramLocation]]. Returns an output [[#PinId]]. | |||
== UnpinProgram == | |||
Takes an input [[#PinId]]. No output. | |||
== SetEnabledProgramVerification == | |||
Takes an input bool. No output. | |||
When the flag is zero, it will set ret=0 instead of ret={error} when verifying the fixed-key [[NPDM]] ACID signature fails. This also skips verifying the [[NCA#Header|NCA Header]] signature using the ACID key. Note that if verifying the fixed-key ACID signature is successful, and verifying the ACID-key NCA header signature fails, it will throw an error and abort. | |||
