idr_destroy(9) [centos man page]

IDR_DESTROY(9)						  Basic Kernel Library Functions					    IDR_DESTROY(9)

idr_destroy - release all cached layers within an idr tree SYNOPSIS
void idr_destroy(struct idr * idp); ARGUMENTS
idp idr handle DESCRIPTION
Free all id mappings and all idp_layers. After this function, idp is completely unused and can be freed / recycled. The caller is responsible for ensuring that no one else accesses idp during or after idr_destroy. A typical clean-up sequence for objects stored in an idr tree will use idr_for_each to free all objects, if necessay, then idr_destroy to free up the id mappings and cached idr_layers. COPYRIGHT

ct_tmpl_activate(3CONTRACT)			       Contract Management Library Functions			       ct_tmpl_activate(3CONTRACT)

ct_tmpl_activate, ct_tmpl_clear, ct_tmpl_create, ct_tmpl_set_cookie, ct_tmpl_set_critical, ct_tmpl_set_informative, ct_tmpl_get_cookie, ct_tmpl_get_critical, ct_tmpl_get_informative - common contract template functions SYNOPSIS
cc [ flag... ] file... -D_LARGEFILE64_SOURCE -lcontract [ library... ] #include <libcontract.h> int ct_tmpl_activate(int fd); int ct_tmpl_clear(int fd); int ct_tmpl_create(int fd, ctid_t *idp); int ct_tmpl_set_cookie(int fd, uint64_t cookie); int ct_tmpl_set_critical(int fd, uint_t events); int ct_tmpl_set_informative(int fd, uint_t events); int ct_tmpl_get_cookie(int fd, uint64_t *cookiep); int ct_tmpl_get_critical(int fd, uint_t *eventsp); int ct_tmpl_get_informative(int fd, uint_t *eventsp); 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_CONTRACT_EVENT} was not in the effective set for the calling process.
