c++ - Is there a way to get userstack for all heap userptr -

i reading through article detecting memory leak using windbg. trying find way print userstack userptrs appear when heap filtered block of memory particular size. possible ? looking achieve like:

  foreach(userptr)      dump_to_a_file !heap -p -a userptr 

where userptr is: userptr under

heap_entry size prev flags    userptr usersize - state         003360e0 03f0 0000  [07]   003360e8    01f64 - (busy)         00338060 03f0 03f0  [07]   00338068    01f64 - (busy)         00339fe0 03f0 03f0  [07]   00339fe8    01f64 - (busy) 

i trying in order avoid manual checking thousands of such userptr. give.

this output of !heap -flt s xxx command contains lot of text before , after heap entry table. let's rid of additional text doing hack

.shell -ci "!heap -flt s xxx" find "[" 

now it's quite stable output, can used in foreach loop:

.foreach (userptr {.shell -ci "!heap -flt s xxx" find "["}) { .echo ${userptr}} 

see how splits each line. let's rid of first 4 tokens (entry, size, prev, flags) , last 3 tokens (usersize, -, state) using /ps 4 /ps 7.

.foreach /ps 4 /ps 7 (userptr {.shell -ci "!heap -flt s xxx" find "["}) { .echo ${userptr}} 

now have pure addresses, useful it, !heap -p -a

.foreach /ps 4 /ps 7 (userptr {.shell -ci "!heap -flt s xxx" find "["}) { !heap -p -a ${userptr}} 

to dump file, surround log (.logopen , .logclose):

.logopen d:\debug\logs\heap.log; .foreach /ps 4 /ps 7 (userptr {.shell -ci "!heap -flt s xxx" find "["}) { !heap -p -a ${userptr}}; .logclose 

there go.
