<function name="getinfo" parent="debug" type="libraryfunc"> <description>Returns debug information about a function.</description> <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> </args> <rets> <ret name="" type="table">A table as a <page>Structures/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> </rets> </function> <example> <description>Let's find out information about net.Receive, such as which file it's defined in, the line it starts and the line it ends, and if it's defined in Lua, or C plus additional information.</description> <code>PrintTable( debug.getinfo( net.Receive ) )</code> <outputfixedwidth>Fixed width</outputfixedwidth>⤶ <output> ```⤶ [linedefined] = 7 [currentline] = -1 [func] = function: 0x1a8fae90 [isvararg] = false [namewhat] = [lastlinedefined] = 11 [source] = @lua/includes/modules/net.lua [nups] = 0 [what] = Lua [nparams] = 2 [short_src] = lua/includes/modules/net.lua ```⤶ </output> </example>
