Is there any command that prints library info? (C++)





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;

Is there any command (in C++) that prints which libraries are available or/and info about how to use a specific library?



I am asking this question because, in a programming language like Python, help() is a useful function (when internet connection is not available for example):



>>> import random

>>> help(random)

"Help on module random: (...)"





c++

    No such thing built into the standard C++ language or library.

    Dynamic languages such as Python usually have a REPL because statements can be executed independently. This does not exist natively for C++ due to its static nature. The only way to know what libraries/include files are available is to look on disk for the directories where they are stored (eg. /usr/include, /usr/lib ... ).

  • Many C library functions have man pages...

  • You could spend a long time writing your own function, that parses header files, and reads the documentation. There are better solutions. Many IDEs can take you right to the function/type in the header file with a shortcut click, like cmd + rmb in Xcode. stdlib doesn't have a documentation in the provided header files by Xcode.

Short answer: No, there is no help function per se in the C++ language or library.



Long answer: Your intention is probably to learn about some function from the library that you want to use now in your C++ program.



If that is your intention, (viz-e-vie the XY Problem), then indeed there are solutions.




  • On Linux, read (POSIX), we have the wonderful man pages. You can basically lookup any function there, with all its parameters, return types and sometimes even examples.


  • On Windows, we have the MSDN documentation (Correct me if I am wrong, someone. I don't work in that world.)


  • Personally, if I want to see how to use a function, its parameters, return type, etc. whether I am using Qt-Creator or Eclipse, I just hover over the function name and let intellisense do its job. I expect the same to be possible in Visual Studio as well.


  • Press CTRL and click on the function name and mostly you can even jump into the header file and get more intuition about how best to use that particular function.

            Monofisismo

            Image
            Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri...

            Image
            Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México...
