NTSTATUS
NTAPI
PspSetLdtSize(
   IN PEPROCESS Process,
   IN PROCESS_LDT_SIZE LdtSize,
   IN ULONG InformationLength)
      

Process is a pointer to a Executive process (EPROCESS). LdtSize is the Local Descriptor Table (LDT) size pointed by its particular structure -- PROCESS_LDT_SIZE. InformationLength is the length size, in bytes, pointed by LdtSize parameter. The function is internally called by NtSetInformationProess() when ProcessLdtSize information class is invoked. The function returns STATUS_SUCCESS if the size of LDT of a process has been set. Otherwise the function will return STATUS_INFO_LENGTH_MISMATCH if the information length size doesn't match with the actual information parameter argument, LdtSize, STATUS_INVALID_LDT_SIZE or STATUS_NO_LDT if the given process doesn't have a LDT.
