 DESCRIPTION

These functions operate on contract template file descriptors obtained from the
contract(5) file system.

The ct_tmpl_activate() function makes the template referenced by the file
descriptor fd the active template for the calling thread.

The ct_tmpl_clear() function clears calling thread's active template.

The ct_tmpl_create() function uses the template referenced by the file
descriptor fd to create a new contract. If successful, the ID of the
newly created contract is placed in *idp.

The ct_tmpl_set_cookie() and ct_tmpl_get_cookie() functions write
and read the cookie term of a contract template. The cookie term is ignored by
the system, except to include its value in a resulting contract's status
object. The default cookie term is 0.

The ct_tmpl_set_critical() and ct_tmpl_get_critical() functions
write and read the critical event set term. The value is a collection of bits
as described in the contract type's manual page.

The ct_tmpl_set_informative() and ct_tmpl_get_informative()
functions write and read the informative event set term. The value is a
collection of bits as described in the contract type's manual page.
 RETURN VALUES

Upon successful completion, ct_tmpl_activate(), ct_tmpl_create(),
ct_tmpl_set_cookie(), ct_tmpl_get_cookie(),
ct_tmpl_set_critical(), ct_tmpl_get_critical(),
ct_tmpl_set_informative(), and ct_tmpl_get_informative() return 0.
Otherwise, they return a non-zero error value.
 ERRORS

The ct_tmpl_create() function will fail if:
ERANGE

The terms specified in the template were unsatisfied at the time of the call.


EAGAIN

The project.max-contracts resource control would have been
exceeded.


The ct_tmpl_set_critical() and ct_tmpl_set_informative() functions
will fail if:
EINVAL

An invalid event was specified.


The ct_tmpl_set_critical() function will fail if:
EPERM

One of the specified events was disallowed given other contract terms (see
contract(5)) and {PRIV_CONTRACT_EVENT} was not in the effective set
for the calling process.
