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.

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.

On New3DS, IDs 2 and 3 are also valid, referring to the 2 additional CPU cores) 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).

The thread priority value must be in the range 0x0..0x3F. Otherwise, error 0xE0E01BFD is returned.
