TT_PROC_ATTACH_NOSTOP
).
[EINVAL] request is an illegal number.
[EINVAL] A non-zero value has been passed in a parameter expecting a zero value or vice-

[EINVAL] Size too large for data transfer.
[EINVAL] Invalid signal number.
[EINVAL] Misaligned request or not a word multiple (

[EINVAL] Invalid signal (
TT_LWP_CONTINUE

TT_LWP_WUREGS.
[EINVAL] The core file argument to a TT_PROC_CORE request exists and is not a regular file.
[EINVAL] The data argument to
TT_VEC_GENERIC
is greater than TT_VEC_MAX.
[EINVAL] An invalid request is specified in the
ttv_req field of a tt_vec_t passed to
TT_VEC_GENERIC.
[EINVAL] Undocumented fields in a
tt_vec_t passed to
TT_VEC_GENERIC are not 0

[EINVAL] The
ttvr_count or ttvr_ret1 field of a tt_vec_res_t passed to
