- * Lazy Dynamic Linking Support
- *
- * This header file is meant to be included multiple times.
- *
- * It is used to define function pointers to symbols in external
- * shared objects (Unix dynamic libraries) which will be lazily resolved
- * at runtime, by calling a specific initialization function.
- *
- * You must define, before including this header, a DYNLINK_FUNCTIONS
- * macro which must contain a sequence of DYNLINK_FUNC(ret,name,sig)
- * statements.
- *
- * In each statement, 'ret' is a function return type, 'name' is
- * the function's name as provided by the library, and 'sig' is
- * the function signature, including enclosing parentheses.
- *
- * Here's an example:
- *
- *  #define DYNLINK_FUNCTIONS \
- *     DYNLINK_FUNC(int,open,(const char*, int)) \
- *     DYNLINK_FUNC(int,read,(int,char*,int)) \
- *     DYNLINK_FUNC(int,close,(int)) \
- *
- *
- * You must also define a DYNLINK_FUNCTIONS_INIT macro which contains the
- * name of a generated function used to initialize the function pointers.
- * (see below)
