rsrcdbmgr_destroy()

QNX SDP8.0C Library ReferenceAPIDeveloper

Destroy a system resource

Synopsis:

#include <sys/rsrcdbmgr.h>

int rsrcdbmgr_destroy( rsrc_alloc_t *item,
                       int count );

Arguments:

item: An array of rsrc_alloc_t structures that describe the resources that you want to destroy. For more information about this structure, see the documentation for rsrcdbmgr_create().
count: The number of entries in the array.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The rsrcdbmgr_destroy() function removes count system resources that are defined in the array item.

Note:

In order to successfully use the rsrcdbmgr_*() functions to modify the resource database, your process must have the PROCMGR_AID_RSRCDBMGR ability enabled. For more information, see procmgr_ability().

Returns:

EOK: Success.
-1: An error occurred; errno is set.

Errors:

EINTR: The call was interrupted by a signal.
EINVAL: Invalid argument, or the resource is in use.
ENOMEM: Insufficient memory to allocate internal data structures.
EPERM: The calling process doesn't have the required permission; see procmgr_ability().

Examples:

See the example in rsrcdbmgr_create().

Classification:


Safety:
Cancellation point	Yes
Signal handler	Yes
Thread	Yes
