lh_register_onfatal()

void lh_register_onfatal

(

lh_fatalfun *

onfatal

)

Register a function that is called on fatal errors.

Use NULL for the default handler (outputs the error to stderr and exits)

• ENOMEM : cannot allocate more memory.
• EFAULT : internal error when trying jump into invalid stack frames.
• ENOTSUP: trying to generally resume a continuation that where the operation was registered with OP_TAIL or OP_THROW.
• ENOSYS : an operation was called but no handler was found for it.
• EINVAL : invalid arguments for an operation.
