C23 has added new format specifiers for exact-width integer types, least-width integer types, et cetera. For instance, `%w32d` for `uint32_t`, `%w64d` for `uint64_t` et cetera, which means that we can say goodbye to the `PRI*` macros. I believe the documentation for `fprintf()` would have this inform...

Should I: Include the header that was used during development with the code? Have an install.sh script (for UNIX and UNIX-like operating systems) that would wget the header during installati...

| Question | — |
Are these two function pointer declarations equivalent? Say I have two functions: ```c FILE getinput(const char fname[static 1]); FILE getoutput(const char fname[static 1]); ``` And I wish to declare a function pointer and assign it the result of some processing which shall be called later. Are these two declarations: ```c int foo(FILE ,... (more) |

How do you suggest formatting `200819` in `#define _POSIX_C_SOURCE 200819`?

There is no platform independent function copy files in ISO C Standard or ISO POSIX Standard. There's the usual `open()` + `read()` + `write()` + `fstat()` + `fchmod()` method, which is portable, but requires all bytes to be dragged to userspace. And it also has 5 syscalls instead of 1-2. (more) |

| Question | — |
What's the fastest way to copy, preserving file attributes, on each platform? I am looking copy files platform-dependently on Linux, Oracle Solaris, MacOS, BSDs, and Windows. I have found some system calls for each platform, namely `sendfile()`, `copyfilerange()`, `fcopyfile()`, `CopyFile()` et cetera. But some of them are documented to copy file attributes, whilst some are... (more) |

Testing an opaque type's internals First: What is an opaque pointer in C? Now when it comes to testing such a type, I know of 3 ways: 1. Include the source file (the one containing the definition of the type and the functions that work with it) directory into the test source file. (This is the easiest, but often discouraged with...

A small header-only input output library The library (inspired by stb libraries) attempts to provide some commonly used functions (reading a file into memory, determining the size of a file) that are missing from the C standard library portably (for my own use cases).

About mixing indentation styles, I was following [K&R](https://en.wikipedia.org/wiki/Indentation_style#K&R_style), where *each function has its opening brace at the next line*.
