UDataFileAccess
Possible settings for udata_setFileAccess()
@ UDATA_FILE_ACCESS_COUNT
Number of real UDataFileAccess values.
@ UDATA_ONLY_PACKAGES
ICU only loads data from packages, not from single files.
@ UDATA_DEFAULT_ACCESS
An alias for the default access mode.
@ UDATA_FILES_FIRST
ICU looks for data in single files first, then in packages.
@ UDATA_PACKAGES_FIRST
ICU loads data from packages first, and only from single files if the data cannot be found in a packa...
@ UDATA_NO_FILES
ICU does not access the file system for data loading.
U_CAPI UDataMemory * udata_openChoice(const char *path, const char *type, const char *name, UDataMemoryIsAcceptable *isAcceptable, void *context, UErrorCode *pErrorCode)
Data loading function.
U_CAPI void udata_getInfo(UDataMemory *pData, UDataInfo *pInfo)
Get the information from the data memory header.
U_CAPI void udata_setFileAccess(UDataFileAccess access, UErrorCode *status)
This function may be called to control how ICU loads data.
U_CAPI void udata_close(UDataMemory *pData)
Close the data memory.
U_CAPI UDataMemory * udata_open(const char *path, const char *type, const char *name, UErrorCode *pErrorCode)

This is used to end a declaration of a library private ICU C API.
int8_t UBool
The ICU boolean type, a signed-byte integer.
#define U_CAPI
This is used to declare a function as a public ICU C API.
#define U_CDECL_BEGIN
This is used to begin a declaration of a library private ICU C API.
Basic definitions for ICU, for both C and C++ APIs.
UErrorCode
Standard ICU4C error code type, a substitute for exceptions.
