C11(1)                      General Commands Manual                     C11(1)

NAME
     c11 - ANSI (2011) C compiler

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.

BUGS

     "cc:".
