Dec 13, 2011 · For example if you use __FILE__ with your definition to produce a diagnostic in an inline function defined in a header file, the runtime diagnostic will report the name of the file passed to the compiler instead of the name of the include file, whereas the line number would refer to the include file.
6. Consider also using SETX - it will set variable on user or machine (available for all users) level though the variable will be usable with the next opening of the cmd.exe ,so often it can be used together with SET : ::setting variable for the current user. if not defined My_Var (. set "My_Var=My_Value".
The others (__LINE__ and __FILE__) are just fine. It will always report the right file and line (and function if you choose to use __FUNCTION__ / __func__). Optimization is a non-factor since it is a compile time macro expansion; it will never affect performance in any way. __func__ is kind of a problem in C++.
May 30, 2014 · The besty practice is to use '/' and a so called 'raw string' to define file path in Python. path = r"C:/Test.py". However, a normal program may not have the permission to write in the C: drive root directory. You may need to allow your program to do so, or choose something more reasonable since you probably not need to do so.
Nov 13, 2018 · 13. Just add -Dxxx=yy on the command line (xxx the name of the macro and yy the replacement, or just -Dxxx if there is no value). It's not a Makefile command, it's part of the compiler command line options. It means, xxx is the name and yy is the value. For example, #define xxx (yy) is -Dxxx=yy.
This is basically the same as having all template definitions after the class declarations, at the end of the file. This is what I do, now. Have one "header" and one "cpp": file.h and file.cpp. Then, you do some explicit instantiation at the end of the .cpp file. The .cpp has to be compiled and linked.
163. Javac doesn't actively prohibit this, but it does have a limitation that pretty much means that you'd never want to refer to a top-level class from another file unless it has the same name as the file it's in. Suppose you have two files, Foo.java and Bar.java. Foo.java contains: public class Foo.
Jan 11, 2013 · 9. If you want to share a define between two source files, move it to a header file and include that header from both source files. mydefines.h: source1.cpp: source2.cpp: You could also specify the define in the compiler command line.
A file is an abstraction. It's an adress somewhere in memory that indicates the first byte in a series of bytes (it can also be fragmented if it's a large file). A stream is also a memory location where bytes are written and bytes are read. In that sense, it is like a file in that you can write and read from it.
Jan 8, 2018 · 5. Usually a reserved value indicates that at some point in the past, perhaps in a released version of Windows that has long since been deprecated, or perhaps in a development version that was never publicly released, that value was used for some purpose, but the value no longer has meaning. By marking the value as reserved, future developers ...
