Raw bindings to jemalloc
Structs
Extent lifetime management functions.
Constants
Initialize newly allocated memory to contain zero bytes.
Statics
Allows overriding the function which emits the text strings forming the
errors and warnings if for some reason the
STDERR_FILENO
file descriptor
is not suitable for this.Functions
Align the memory allocation to start at an address that is a multiple of
align
,
where a is a power of two.Use the arena specified by the index
a
.Align the memory allocation to start at an address that is a
multiple of
1 << la
.Use the thread-specific cache (tcache) specified by the identifier
tc
.Do not use a thread-specific cache (tcache).
Allocates
size
bytes of memory at an address which is a multiple of
alignment
.Allocates zero-initialized space for an array of
number
objects, each
of whose size is size
.Deallocates previously-allocated memory region referenced by
ptr
.free⚠
Deallocates previously-allocated memory region referenced by
ptr
.General interface for introspecting the memory allocator, as well as
setting modifiable parameters and triggering actions.
Like
mallctl
but taking a mib
as input instead of a name.Translates a name to a “Management Information Base” (MIB) that can be
passed repeatedly to
mallctlbymib
.Allocates
size
bytes of uninitialized memory.Writes summary statistics via the
write_cb
callback function pointer
and cbopaque
data passed to write_cb
, or malloc_message
if write_cb
is null.Returns the real size of the previously-allocated memory region
referenced by
ptr
.Allocates at least
size
bytes of memory according to flags
.Returns the real size of the allocation that would result from a
mallocx
function call with the same arguments.Allocates
size
bytes of memory at an address which is a multiple of
alignment
and is placed in *ptr
.Resizes the previously-allocated memory region referenced by
ptr
to be
at least size
bytes.Resizes the previously-allocated memory region referenced by
ptr
to
size
bytes.Returns the real size of the previously-allocated memory region
referenced by
ptr
.Deallocates previously-allocated memory region referenced by
ptr
with
size
hint.Resizes the previously-allocated memory region referenced by
ptr
in
place to be at least size
bytes, returning the real size of the
allocation.Type Definitions
