Function Documentation

APU_DECLARE (  apr_size_t   ) 
 

Compute the required overallocation of memory needed to fit n allocs

Parameters:
n The number of alloc/calloc regions desired

Definition at line 411 of file apr_rmm.c.

APU_DECLARE (  void *   ) 
 

Retrieve the physical address of a relocatable allocation of memory

Parameters:
rmm The relocatable memory block
entity The memory allocation to free
Returns:
address The address, aligned with APR_ALIGN_DEFAULT.

APU_DECLARE (  apr_rmm_off_t   ) 
 

Allocate memory from the block of relocatable memory.

Parameters:
rmm The relocatable memory block
reqsize How much memory to allocate

Definition at line 297 of file apr_rmm.c.

Here is the call graph for this function:

APU_DECLARE (  apr_status_t   ) 
 

Initialize a relocatable memory block to be managed by the apr_rmm API.

Parameters:
rmm The relocatable memory block
lock An apr_anylock_t of the appropriate type of lock
membuf The block of relocateable memory to be managed
memsize The size of relocateable memory block to be managed
cont The pool to use for local storage and management
Remarks:
Both
Parameters:
membuf and
memsize must be aligned (for instance using APR_ALIGN_DEFAULT).
