Using underline _ at the beginning of parameters
In programing languages like c++, does the parameters beginning with _ (like _view=...this was just an example) represent any special condition or meaning? Like is it a tradition to use some specific kind of variables beginning with underline? Or is it a tradition between programmers to begin a parameter with underline for some reasons?
I do recall something as a tradition but I don't remember what it was!!!!!!

it depends on the API itself for example the Win32 function EnumWindows()
takes as a first parameter a 32 bit pointer to a function ...
you should know that by looking at the prefix of the parameter name "lp" which always refers to Long Pointer
Decode the following to 8-Bit ASCII : 01001001 01110011 01101100 01100001 01101101 00100000 01101001 01110011 00100000 01110100 01101000 01100101 00100000 01110011 01101111 01101100 01110101 01110100 01101001 01101111 01101110
