4.5 fluke_region_create_hash: create a new memory region with a given hash value

SYNOPSIS

fluke_error_t fluke_region_create_hash( fluke_region_t *new_region, integer_t *hash);

DESCRIPTION

Creates a new empty region with the specified hash value. The created region has no virtual memory association, before it can be mapped the region must be associated with a task address space using fluke_region_set_state.

On a call, hash is a pointer to the hash value to set. If the pointer or the value is zero, the implementation will choose a default value. On a successful return, a non-zero pointer will contain the hash value set.

PARAMETERS

new_region
A pointer to the address in the current task's address space at which to create the new region object. There must be no existing Fluke objects at this location; otherwise the results are undefined.
hash
On entry, a pointer to the desired hash value to set. On return, the hash value used.

ERRORS

If any of the following errors is detected, the appropriate error code is returned: All of these have an implicit FLUKE_ prefix.
NO_MEMORY
Insufficient resources were available.

If any of the following errors is detected by the Fluke implementation, it causes the current thread to take a synchronous exception with one of the following codes. All of these have an implicit FLUKE_INSANITY_ prefix.
OBJECT_EXISTS
An object already exists at the location pointed to by new_region.
NOT_ALIGNED
new_region is not properly aligned for a region object.
