<h3><a name="ImportantNotesDeprecatedAPI" href=
"#ImportantNotesDeprecatedAPI">Methods for enabling deprecated
APIs</a></h3>
<h4>C</h4>
<p>Some deprecated C APIs can be enabled without recompiling the ICU
libraries. This can be achieved by defining certain symbols before
including the ICU header files. For example, to enable deprecated C APIs
for formatting.</p>
<pre>
<samp>#ifndef U_USE_DEPRECATED_FORMAT_API
# define U_USE_DEPRECATED_FORMAT_API 1
#endif
#include &quot;unicode/udat.h&quot;
int main(){
UDateFormat *def, *fr, *fr_pat ;
UErrorCode status = U_ZERO_ERROR;
UChar temp[30];
fr = udat_open(UDAT_FULL, UDAT_DEFAULT, &quot;fr_FR&quot;, NULL,0, &amp;status);
if(U_FAILURE(status)){
printf(&quot;Error creating the french dateformat using full time style\n %s\n&quot;,
myErrorName(status) );
}
/* This is supposed to open default date format,
but later on it treats it like it is &quot;en_US&quot;.
This is very bad when you try to run the tests
on a machine where the default locale is NOT &quot;en_US&quot;
*/
def = udat_open(UDAT_SHORT, UDAT_SHORT, &quot;en_US&quot;, NULL, 0, &amp;status);
if(U_FAILURE(status)){
.... /* handle the error */
}
}</samp>
</pre>
<h4>C++</h4>
<p>Deprecated C++ APIs cannot be enabled without recompiling ICU libraries.
Every service has a specific symbol that should be defined to enable the
deprecated API of that service. For example: To enable deprecated APIs in
transliteration service, the U_USE_DEPRECATED_TRANSLITERATOR_API symbol
should be defined before compiling ICU.</p>
