#define U_CAPI
This is used to declare a function as a public ICU C API.
Definition: umachine.h:135
void uenum_close(UEnumeration *en)
Disposes of resources in use by the iterator.
struct UEnumeration UEnumeration
structure representing an enumeration object instance
Definition: uenum.h:39
const char * uenum_next(UEnumeration *en, int32_t *resultLength, UErrorCode *status)
Returns the next element in the iterator's list.
#define U_NAMESPACE_BEGIN
This is used to begin a declaration of a public ICU C++ API.
Definition: uversion.h:131
const UChar * uenum_unext(UEnumeration *en, int32_t *resultLength, UErrorCode *status)
Returns the next element in the iterator's list.
#define U_NAMESPACE_QUALIFIER
This is used to qualify that a function or class is part of the public ICU C++ API namespace...
Definition: uversion.h:134
C++ API: "Smart pointers" for use with and in ICU4C C++ code.
int32_t uenum_count(UEnumeration *en, UErrorCode *status)
Returns the number of elements that the iterator traverses.
#define U_EXPORT2
Definition: platform.h:314
uint16_t UChar
Define UChar to be wchar_t if that is 16 bits wide; always assumed to be unsigned.
Definition: umachine.h:325
#define U_NAMESPACE_END
This is used to end a declaration of a public ICU C++ API.
Definition: uversion.h:132
UErrorCode
Error code to replace exception handling, so that the code is compatible with all C++ compilers...
Definition: utypes.h:639
Base class for 'pure' C++ implementations of uenum api.
Definition: strenum.h:55
C++ API: String Enumeration.
Basic definitions for ICU, for both C and C++ APIs.
void uenum_reset(UEnumeration *en, UErrorCode *status)
Resets the iterator to the current list of service IDs.
#define U_STABLE
This is used to declare a function as a stable public ICU C API.
Definition: umachine.h:137
