Detailed Description

Common types used in decoder and encoder API.

Macro Definition Documentation

#define BROTLI_BOOL   int

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);
}
#define BROTLI_FALSE   0

Portable false replacement.

#define BROTLI_TRUE   1

Portable true replacement.

#define TO_BROTLI_BOOL (   X)    (!!(X) ? BROTLI_TRUE : BROTLI_FALSE)

bool to BROTLI_BOOL conversion macros.

Typedef Documentation

typedef void*(* brotli_alloc_func) (void *opaque, size_t size)

Allocating function pointer type.

Parameters
opaquecustom memory manager handle provided by client
sizerequested memory region size; can not be 0
Returns
0 in the case of failure
a valid pointer to a memory region of at least size bytes long otherwise
typedef void(* brotli_free_func) (void *opaque, void *address)

Deallocating function pointer type.

This function SHOULD do nothing if address is 0.

Parameters
opaquecustom memory manager handle provided by client
addressmemory region pointer returned by brotli_alloc_func, or 0
