Dynamic memory management module

Defines memory allocation function for nrf_crypto.

This macro is used internally by nrf_crypto library to allocate temporary memory. It is not intended to be used outside nrf_crypto library. How memory is actually allocated is configured by NRF_CRYPTO_ALLOCATOR definition.

If user macros are selected by NRF_CRYPTO_ALLOCATOR then this macro have to be defined by the user in "nrf_crypto_allocator.h" file. The file will be included into "nrf_crypto_mem.h".

If NRF_CRYPTO_ALLOC_ON_STACK is 1 then this function will allocate data on stack, so make sure that returned pointer is not used outside the caller function.

Parameters

size	Number of bytes to allocate.

Returns

Pointer to newly allocated memory or NULL on error.

Contains 1 if memory allocated by NRF_CRYPTO_ALLOC is on stack or 0 otherwise.

This definition is used internally by nrf_crypto library. It is not intended to be used outside nrf_crypto library.

If user macros are selected by NRF_CRYPTO_ALLOCATOR then this macro have to be defined by the user in "nrf_crypto_allocator.h" file. The file will be included into "nrf_crypto_mem.h".
