The term C11 used in this book refers to the ISO/IEC 9899:2011 C programming language. The term C99 refers to the ISO/IEC 9899:1999 C programming language. The term C90 refers to the ISO/IEC 9899:1990 C programming language.
This compiler supports the language features, as described in Features of C11, of the C11 standard on Oracle Solaris platforms when you specify -std=c11.
Because the compiler also supports traditional K&R C (Kernighan and Ritchie, or pre-ANSI C), it can ease your migration to ISO C.
For information about C90 implementation-specific behavior, see Implementation-Defined ISO/IEC C90 Behavior.
