A portable \fCbool\fP replacement\&. \fBBROTLI_BOOL\fP is a 'documentation' type: actually it is \fCint\fP, but in API it denotes a type, whose only values are \fBBROTLI_TRUE\fP and \fBBROTLI_FALSE\fP\&.
|
|
.PP
|
|
\fBBROTLI_BOOL\fP values passed to Brotli should either be \fBBROTLI_TRUE\fP or \fBBROTLI_FALSE\fP, or be a result of \fBTO_BROTLI_BOOL\fP macros\&.
|
|
.PP
|
|
\fBBROTLI_BOOL\fP values returned by Brotli should not be tested for equality with \fCtrue\fP, \fCfalse\fP, \fBBROTLI_TRUE\fP, \fBBROTLI_FALSE\fP, but rather should be evaluated, for example:
|
|
.PP
|
|
.nf
|
|
if (SomeBrotliFunction(encoder, BROTLI_TRUE) &&
|
|
!OtherBrotliFunction(decoder, BROTLI_FALSE)) {
|
|
bool x = !!YetAnotherBrotliFunction(encoder, TO_BROLTI_BOOL(2 * 2 == 4));
|
|
DoSomething(x);
|
|
}
