configuration of the SSL connection, as the caller is responsible to create a
connection context using
`SSL_new()`
and configure it as required.
## Allocator injection
Hiredis uses a pass-thru structure of function pointers defined in
[
alloc.h
](
https://github.com/redis/hiredis/blob/f5d25850/alloc.h#L41
)
that conttain
the currently configured allocation and deallocation functions. By default they
just point to libc (
`malloc`
,
`calloc`
,
`realloc`
, etc).
### Overriding
One can override the allocators like so:
```
c
hiredisAllocFuncs
myfuncs
=
{
.
mallocFn
=
my_malloc
,
.
callocFn
=
my_calloc
,
.
reallocFn
=
my_realloc
,
.
strdupFn
=
my_strdup
,
.
freeFn
=
my_free
,
};
// Override allocators (function returns current allocators if needed)
hiredisAllocFuncs
orig
=
hiredisSetAllocators
(
&
myfuncs
);
```
To reset the allocators to their default libc function simply call:
```
c
hiredisResetAllocators
();
```
