typedef void *(* brotli_alloc_func) (void *opaque, size_t size)
Allocating function pointer type.
typedef void(* brotli_free_func) (void *opaque, void *address)
Deallocating function pointer type.

A portable bool replacement. BROTLI_BOOL is a 'documentation' type: actually it is int, but in API it denotes a type, whose only values are BROTLI_TRUE and BROTLI_FALSE.

BROTLI_BOOL values passed to Brotli should either be BROTLI_TRUE or BROTLI_FALSE, or be a result of TO_BROTLI_BOOL macros.

BROTLI_BOOL values returned by Brotli should not be tested for equality with true, false, BROTLI_TRUE, BROTLI_FALSE, but rather should be evaluated, for example:

if (SomeBrotliFunction(encoder, BROTLI_TRUE) &&
    !OtherBrotliFunction(decoder, BROTLI_FALSE)) {
  bool x = !!YetAnotherBrotliFunction(encoder, TO_BROLTI_BOOL(2 * 2 == 4));
  DoSomething(x);
}

Portable false replacement.

Portable true replacement.

bool to BROTLI_BOOL conversion macros.

Allocating function pointer type.

Parameters:

opaque custom memory manager handle provided by client
size requested memory region size; can not be 0

Returns:

Deallocating function pointer type. This function SHOULD do nothing if address is 0.

Parameters:

opaque custom memory manager handle provided by client
address memory region pointer returned by brotli_alloc_func, or 0
