~~== CreateThread ==~~

−

~~R0=s32 threadpriority~~

−

~~R1=func entrypoint~~

−

~~R2=u32 arg~~

−

~~R3=u32 stacktop~~

−

~~R4=s32 processorid~~

−

~~Result result=R0~~

−

~~Handle* thread=R1~~

−

The processorid parameter specifies which processor the thread can run on. Non-negative values correspond to a specific CPU. (e.g. 0 for the Appcore and 1 for the Syscore on Old3DS) Special value -1 means all CPUs, and -2 means the default CPU for the process (Read from the [[NCCH/Extended Header|Exheader]], usually 0 for applications, 1 for system services). Games usually create threads using -2.

−

~~With the Old3DS kernel, the s32 processorid must be <=2.~~

−

With the New3DS kernel: processorid must be <= <total cores(MPCore "SCU Configuration Register" CPU number value + 1)>. When processorid==0x2 and the process is not an APPLICATION mem-region process, exheader kernel-flags bitmask 0x2000 must be set otherwise error 0xD9001BEA is returned. When processorid==0x3 and the process is not an APPLICATION mem-region process, error 0xD9001BEA is returned. These are the only restriction checks done by the kernel for processorid.

−

~~The thread priority value must be in the following range: 0x0..0x3F.~~

−

~~The stacktop must be aligned to 0x8-bytes, otherwise when not aligned to 0x8-bytes the ARM11 kernel clears the low 3-bits of the stacktop address.~~
