### NAME

c99 - ANSI (1999) C compiler

### SYNOPSIS

c99 [-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 9899:1999 (``ISO C99'') specification.

This includes inline functions, variable-length arrays, support for one-line comments beginning with //, disabling non-ANSI compiler features (such as asm, typeof, and the $ character in identifiers), and definition of the preprocessor symbol ```__STRICT_ANSI__`.

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.

### SEE ALSO

cc(1)

### STANDARDS

c99 conforms to IEEE Std 1003.2-1992 (``POSIX.2'') .

### HISTORY

c99 first appeared in NetBSD5.0.

### BUGS

Since c99 is a shell wrapper script to cc, compile errors are prefixed by "cc:".
