Typedef Documentation

  typedef void *(* jwt_malloc_t) (size_t)

Prototype for malloc(3).

Function Documentation

  void jwt_get_alloc (jwt_malloc_t * pmalloc, jwt_free_t * pfree)
Get functions used for allocating and freeing memory.

Parameters
    pmalloc Pointer to malloc function output variable, or NULL
    pfree Pointer to free function output variable, or NULL

  int jwt_set_alloc (jwt_malloc_t pmalloc, jwt_free_t pfree)

Set functions to be used for memory management. By default, LibJWT uses malloc and free for memory management. This function allows the user of the library to specify its own memory management functions. This is especially useful on Windows where mismatches in runtimes across DLLs can cause problems.

The caller can specify either a valid function pointer for any of the parameters or NULL to use the corresponding default allocator function.

Note
    This function will also set the memory allocator for the Jansson library.

Parameters
    pmalloc The function to use for allocating memory or NULL to use malloc
    pfree The function to use for freeing memory or NULL to use free

Returns
    0 on success or errno otherwise.
