std::placeholders(3)
π std::placeholders β the manual page, bestie edition π
okay so this is std::placeholders, from section 3 of the Library Functions Manual β yes, the Library Functions Manual, we're in the big leagues now. it's the ISO C++ 2011 namespace where all the std::bind placeholders live. that's it. that's the whole vibe. π
β¨ NAME β¨
std::placeholders β the ISO C++ 2011 namespace for std::bind placeholders. literally just a little namespace full of numbered little guys who hold your arguments for you. no cap.
πΈ SYNOPSIS πΈ
π¦ Variables
these are all const and they are all living in this namespace, and yes, there really are 29 of them, and yes, the ordering here is alphabetical-string-wise, not numerically, and no, I will not be reordering them, because that's how the page has them and I am nothing if not faithful. π
const _Placeholder< 1 > _1
const _Placeholder< 10 > _10
const _Placeholder< 11 > _11
const _Placeholder< 12 > _12
const _Placeholder< 13 > _13
const _Placeholder< 14 > _14
const _Placeholder< 15 > _15
const _Placeholder< 16 > _16
const _Placeholder< 17 > _17
const _Placeholder< 18 > _18
const _Placeholder< 19 > _19
const _Placeholder< 2 > _2
const _Placeholder< 20 > _20
const _Placeholder< 21 > _21
const _Placeholder< 22 > _22
const _Placeholder< 23 > _23
const _Placeholder< 24 > _24
const _Placeholder< 25 > _25
const _Placeholder< 26 > _26
const _Placeholder< 27 > _27
const _Placeholder< 28 > _28
const _Placeholder< 29 > _29
const _Placeholder< 3 > _3
const _Placeholder< 4 > _4
const _Placeholder< 5 > _5
const _Placeholder< 6 > _6
const _Placeholder< 7 > _7
const _Placeholder< 8 > _8
const _Placeholder< 9 > _9
so yeah. _1 through _29, every single one a const _Placeholder< N > with its own little number baked in. π§
π Detailed Description π
ISO C++ 2011 namespace for std::bind placeholders.
that's the whole description, bestie. it's giving "minimalist" and honestly? iconic. it's a namespace, it holds placeholders, it was standardized in 2011, periodt. π
π Since
C++11 β yeah, she's been around since C++11, she's a legacy icon, an OG. π«Ά
π Author π
Generated automatically by Doxygen for libstdc++ from the source code.
not a human author, not a person with feelings, just Doxygen doing its thing for libstdc++. nobody hand-wrote this one. it's a machine-generated little page and we love her anyway. π
and that's the whole page! it came to you straight from libstdc++, section 3 of the Library Functions Manual, std::placeholders(3) β so next time you're passing _1 into a std::bind call, just know she's a real one, she's const, and she's been waiting since C++11 for her moment. slay. πβ¨
