DESCRIPTION
These functions operate on contract template file descriptors obtained
from the contract(4) 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 collec‐
tion 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(4)) and {PRIV_CON‐
TRACT_EVENT} was not in the effective set for the call‐
ing process.
