2005-11-14 The C standard library or libc is the standard library for the C programming language, as specified in the ISO C standard. Starting from the original ANSI C standard, it was developed at the same time as the C library POSIX specification, which is a superset of it. Since ANSI C was adopted by the International Organization for Standardization, the C standard library is also called the ISO C c documentation: Getting started with C Language. Notice that the C programming language was not standardized at the time of writing the first edition of this book (1978), and that this program will probably not compile on most modern compilers unless they are instructed to accept C90 code.

If you use the pow() macro, the type of the argument determines which version of the function is selected. See Type-generic math for details.

tgmath implementation, if available, is supplied with the math library on your system, e.g. glibc for linux. Not part of this C compiler. Off Topic for this group, maybe partly on topic for gcc.help mailing list, more so for a forum associated with your OS. The header includes the headers and and defines several type-generic macros.

Generic macros are similar to the ISO/IEC 9899:1999 standard library masking macros, though the semantic types of return values differ. 2020-09-11 Instantly share code, notes, and snippets. petreleon / tgmath.h.

I'm looking at tgmath.h and trying to understand exactly how it selects the correct function based on the size of the input value.. The special sauce seems to be this __tg_promote macro but the deeper I dig the deeper this puzzle gets. Does anyone have a short answer to what __tg_promote actually does?

For ISO C Standard 11 (C11) and later, the header, in addition to including and , provides macros that invoke a corresponding math function based on the types of the parameters. C runtime library math functions come in real and complex variants.
