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.


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.


The ct_tmpl_create() function will fail if:


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


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

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


An invalid event was specified.

The ct_tmpl_set_critical() function will fail if:


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.
