miruga27 0:7fb6877b5d7c 24 *
miruga27 0:7fb6877b5d7c 25 * System dependent library loading routines
miruga27 0:7fb6877b5d7c 26 *
miruga27 0:7fb6877b5d7c 27 * Some things to keep in mind:
miruga27 0:7fb6877b5d7c 28 * \li These functions only work on C function names. Other languages may
miruga27 0:7fb6877b5d7c 29 * have name mangling and intrinsic language support that varies from
miruga27 0:7fb6877b5d7c 30 * compiler to compiler.
miruga27 0:7fb6877b5d7c 31 * \li Make sure you declare your function pointers with the same calling
miruga27 0:7fb6877b5d7c 32 * convention as the actual library function. Your code will crash
miruga27 0:7fb6877b5d7c 33 * mysteriously if you do not do this.
miruga27 0:7fb6877b5d7c 34 * \li Avoid namespace collisions. If you load a symbol from the library,
miruga27 0:7fb6877b5d7c 35 * it is not defined whether or not it goes into the global symbol
miruga27 0:7fb6877b5d7c 36 * namespace for the application. If it does and it conflicts with
miruga27 0:7fb6877b5d7c 37 * symbols in your code or other shared libraries, you will not get
miruga27 0:7fb6877b5d7c 38 * the results you expect. :)
