A keyword is a special identifier with a particular meaning to the syntactical part of the compiler. The following tokens (entirely in lower case only) are reserved for use as keywords, and cannot be used for any other purpose.
| asm | auto 1 2 3 | break | case | char 1 2 | const | continue |
| default | do | double | else | enum | extern 1 2 3 | float |
| for | global 1 | goto 1 2 3 | if | inline | int | long 1 2 |
| register 1 2 | return | short | signed | switch | sizeof | static 1 2 3 4 |
| struct | typedef | union | unsigned | void | volatile | while |
In addition to these keywords, some compilers for particular machines also use, but are not limited to, the following keywords:
| cdecl | far | fortran | huge | near | pascal | interrupt |
Note that these represent non portable extensions to the 'C' language. Most compilers which have such extensions, have a means (e.g. a command line switch or a pragma) which will cause warning messages to be generated if any such extension is used.
