Function Documentation

void* invt_allocate_aux

(

size_t

user_nbytes

)

Allocate nbytes of memory, throwing an exception in case of failure.

Definition at line 515 of file AllocAux.C.

Referenced by invt_allocate().

void invt_allocation_allow_caching

(

bool

on

)

Turn on/off caching of memory blocks of commonly-used sizes.

Definition at line 533 of file AllocAux.C.

Referenced by ModelManager::paramChanged().

void invt_allocation_debug_print

(

bool

print

)

Turn on/off memory-allocation debugging statements.

If on, each invt_allocate() and invt_deallocate() call will print some stats about the memory block being currently allocated/deallocated, as well as some general stats about the total amount of memory allocated and the amount of memory currently in use

Definition at line 539 of file AllocAux.C.

void invt_allocation_release_free_mem

(

)

Released any cached free memory blocks (e.g. to conserve memory).

Definition at line 527 of file AllocAux.C.

void invt_allocation_set_stats_units

(

const size_t

units

)

Set the units to be used by default in invt_allocation_show_stats().

Definition at line 553 of file AllocAux.C.

void invt_allocation_show_stats	(	int	verbosity = 0,
		const char *	pfx = 0,
		const size_t	units = 0
	)

Print current stats for whatever memory allocator is in use.

Parameters:

	verbosity	If greater than 0, will request additional stats to be displayed
	pfx	If non-null, will be printed at the beginning of each stats line.
	units	If non-zero, allocated memory blocks will be listed as multiples of this number of bytes; otherwise memory blocks will be listed as multiples of the units specified in the most recent call to invt_allocation_set_stats_units().

void invt_deallocate_aux

(

void *

mem

)
