Functions

void * wolfSSL_Malloc (size_t size, void *heap, int type)
 This function is similar to malloc(), but calls the memory allocation function which wolfSSL has been configured to use. By default, wolfSSL uses malloc(). This can be changed using the wolfSSL memory abstraction layer - see wolfSSL_SetAllocators(). Note wolfSSL_Malloc is not called directly by wolfSSL, but instead called by macro XMALLOC. For the default build only the size argument exists. If using WOLFSSL_STATIC_MEMORY build then heap and type arguments are included. More...
 
void wolfSSL_Free (void *ptr, void *heap, int type)
 This function is similar to free(), but calls the memory free function which wolfSSL has been configured to use. By default, wolfSSL uses free(). This can be changed using the wolfSSL memory abstraction layer - see wolfSSL_SetAllocators(). Note wolfSSL_Free is not called directly by wolfSSL, but instead called by macro XFREE. For the default build only the ptr argument exists. If using WOLFSSL_STATIC_MEMORY build then heap and type arguments are included. More...
 
void * wolfSSL_Realloc (void *ptr, size_t size, void *heap, int type)
 This function is similar to realloc(), but calls the memory re-allocation function which wolfSSL has been configured to use. By default, wolfSSL uses realloc(). This can be changed using the wolfSSL memory abstraction layer - see wolfSSL_SetAllocators(). Note wolfSSL_Realloc is not called directly by wolfSSL, but instead called by macro XREALLOC. For the default build only the size argument exists. If using WOLFSSL_STATIC_MEMORY build then heap and type arguments are included. More...
 
int wolfSSL_SetAllocators (wolfSSL_Malloc_cb, wolfSSL_Free_cb, wolfSSL_Realloc_cb)
 This function registers the allocation functions used by wolfSSL. By default, if the system supports it, malloc/free and realloc are used. Using this function allows the user at runtime to install their own memory handlers. More...
 
int wolfSSL_StaticBufferSz (byte *buffer, word32 sz, int flag)
 This function is available when static memory feature is used (–enable-staticmemory). It gives the optimum buffer size for memory “buckets”. This allows for a way to compute buffer size so that no extra unused memory is left at the end after it has been partitioned. The returned value, if positive, is the computed buffer size to use. More...
 
int wolfSSL_MemoryPaddingSz (void)
 This function is available when static memory feature is used (–enable-staticmemory). It gives the size of padding needed for each partition of memory. This padding size will be the size needed to contain a memory management structure along with any extra for memory alignment. More...
