Tool table access interface

Hallo,
please, can you help me how to access to tooltable in latest LCNC master version? In past, I have used emcStatus->io.tool.tooltable[pocket]... , but it seems, it is obsolette.
I have tried to compile LCNC with --enable-toolnml, but it is not possible to compile:
/usr/bin/ld: objects/emc/usr_intf/halui.o: in function `main':
/home/lkavan/linuxcnc/linuxcnc-dev/src/emc/usr_intf/halui.cc:2314: undefined reference to `tool_mmap_user()'

I have tried to access tooltable with new mmap, but when I have tried this:

CANON_TOOL_TABLE tdata;
tooldata_get(&tdata,1);

GUI crashes with result: 290056 tooldata_get() not mmapped BYE

I cannot find any docs for how to use new tooltable interface.
Thanx for your help.

 

So, after some research I have found these functions:
toolidx_t tooldata_put(struct CANON_TOOL_TABLE tdata,int idx);
toolidx_t tooldata_get(CANON_TOOL_TABLE* pdata,int idx);

void tooldata_init(bool random_tool_changer);
void tooldata_reset(void);
void tooldata_last_index_set(int idx);
int tooldata_last_index_get(void);
int tooldata_find_index_for_tool(int toolno);
//mmap specific
int tool_mmap_creator(EMC_TOOL_STAT const *ptr,int random_toolchanger);
int tool_mmap_user(void);
void tool_mmap_close(void);
bool tool_mmap_is_random_toolchanger(void);

But I am not sure how to use them right. When I call tooldata_init(0) and then tool_mmap_user() then I am able to read and write from/to tooltable with tooldata_put and tooldata_get Should I call tool_mmap_close() when finished with tooltable access? After this, next access to tooltable crashes GUI.
