<realm>Shared and Menu</realm>⤶
<args>⤶
<arg name="funcOrStackLevel" type="function">Takes either a function or a number representing the stack level as an argument. Stack level 0 always corresponds to the debug.getinfo call, 1 would be the function calling debug.getinfo, and so on.

Returns useful information about that function in a table.</arg>⤶
<arg name="fields" type="string" default="flnSu">A string whose characters specify the information to be retrieved.

* f - Populates the func field.
* l - Populates the currentline field.
* L - Populates the activelines field.
* n - Populates the name and namewhat fields - only works if stack level is passed rather than function pointer.
* S - Populates the location fields (lastlinedefined, linedefined, short_src, source and what).
* u - Populates the argument and upvalue fields (isvararg, nparams, nups)</arg>⤶

<rets>⤶
<ret name="" type="table">A table as a <page>DebugInfo</page> containing information about the function you passed. Can return nil if the stack level didn't point to a valid stack frame.</ret>⤶
