int mbedtls_hardclock_poll ( void *  data,
unsigned char *  output,
size_t  len,
size_t *  olen 
)

mbedtls_timing_hardclock-based entropy poll callback

Definition at line 212 of file entropy_poll.c.

int mbedtls_hardware_poll ( void *  data,
unsigned char *  output,
size_t  len,
size_t *  olen 
)

Entropy poll callback for a hardware source.

Warning:
This is not provided by mbed TLS! See MBEDTLS_ENTROPY_HARDWARE_ALT in config.h.
Note:
This must accept NULL as its first argument.
