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.
void udata_getInfo(UDataMemory *pData, UDataInfo *pInfo)
Get the information from the data memory header.

void udata_setCommonData(const void *data, UErrorCode *err)
This function bypasses the normal ICU data loading process and allows you to force ICU's system data ...
const void * udata_getMemory(UDataMemory *pData)
Get the pointer to the actual data inside the data memory.
UDataMemory * udata_open(const char *path, const char *type, const char *name, UErrorCode *pErrorCode)
Convenience function.
void udata_setFileAccess(UDataFileAccess access, UErrorCode *status)
