The following statement is a part of man 2 fctl.
[EINTR] The argument cmd is invalid.
The argument cmd is F_SETLKW, and the function
was
interrupted by a signal.
Will EINVAL be returned in the case of 'The argument cmd is invalid'?
Will EINTR be returned for F_SETLK?
The following code is sys/kern/kern_descrip.c sys_fcntl():
case F_SETLKW:
flg |= F_WAIT;
/* FALLTHROUGH */
case F_SETLK:
How about it?
