Function esp_idf_sys::mbedtls_entropy_add_source

    ctx: *mut mbedtls_entropy_context,

\brief Adds an entropy source to poll (Thread-safe if MBEDTLS_THREADING_C is enabled)

\param ctx Entropy context \param f_source Entropy function \param p_source Function data \param threshold Minimum required from source before entropy is released ( with mbedtls_entropy_func() ) (in bytes) \param strong MBEDTLS_ENTROPY_SOURCE_STRONG or MBEDTLS_ENTROPY_SOURCE_WEAK. At least one strong source needs to be added. Weaker sources (such as the cycle counter) can be used as a complement.

\return 0 if successful or MBEDTLS_ERR_ENTROPY_MAX_SOURCES
