# 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.
