SYNOPSIS

c11 [-pedantic] [-pedantic-errors] [-D_ANSI_SOURCE] [options ...]

DESCRIPTION

Calls the C compiler (cc) with the given options, using a C language environment compatible with the ISO/IEC 9899:2011 (“ISO C11”) specification.
This includes alignment specification (_Alignas specifier, _Alignof operator), the _Noreturn function specifier, type-generic expressions using the _Generic keyword, multi-threading support, improved unicode handling, anonymous structures and unions, static assertions, exclusive create-and-open mode for fopen(3), the quick_exit(3) function performing minimal cleanup, macros for construction of complex values.
The following options are available:
 
 
-pedantic
Issue extra warnings defined by ANSI for use of non-ANSI features.
 
 
-pedantic-errors
Issue errors instead of warnings that normally would be presented by -pedantic.
 
 
-D_ANSI_SOURCE
Tell the system header file set to use an ANSI-conformant "clean" namespace.
