* This header file is meant to help ensure that engines and
|
|
* infrastructure code do not make use of certain "forbidden" APIs, such
|
|
* as fopen(), setjmp(), etc.
|
|
* This is achieved by re-#defining various symbols to a "garbage"
|
|
* string which then trigers a compiler error.
|
|
*
|
|
* Backend files may #define FORBIDDEN_SYMBOL_ALLOW_ALL if they
|
|
* have to access functions like fopen, fread etc.
|
|
* Regular code, esp. code in engines/, should never do that.

|
|
* By including a space and "!" we try to ensure a compiler error.
|
|
* By using the words "forbidden symbol" we try to make it a bit
|
|
* clearer what is causing the error.
