RtlInitializeUnicodePrefix function (ntifs.h)
The RtlInitializeUnicodePrefix routine initializes a prefix table.
Syntax
NTSYSAPI VOID RtlInitializeUnicodePrefix(
[out] PUNICODE_PREFIX_TABLE PrefixTable
);
Parameters
[out] PrefixTable
Pointer to caller-allocated buffer, which must be at least sizeof(UNICODE_PREFIX_TABLE), for the prefix table header. RtlInitializeUnicodePrefix initializes this header, which should be considered opaque by the caller.
Return value
None
Remarks
File systems must call RtlInitializeUnicodePrefix to initialize the prefix table before using any other Rtl..UnicodePrefix routines on it. The initialized prefix table structure should be considered opaque.
Callers of the Rtl..UnicodePrefix routines are responsible for synchronizing access to the prefix table. A fast mutex is the most efficient synchronization mechanism to use for this purpose.
For information about other string-handling routines, see Run-Time Library (RTL) Routines.
