Vedis C/C++ API Reference - Randomness.

Syntax

int vedis_util_random_string(vedis *pStore,char *zBuf,unsigned int buf_size);
unsigned int vedis_util_random_num(vedis *pStore);

Built-in Randomness.

Description

Vedis is shipped with a high-quality pseudo-random number generator (PRNG). These interfaces allows host-applications to access the same PRNG for other purposes.

vedis_util_random_num() returns a 32-bit unsigned integer between 0 and 0xFFFFFFFF.

vedis_util_random_string() generate a english alphabet based string of length buf_size (last argument). Note that the generated string is not null terminated and the given buffer must be big enough to hold at least 3 bytes.

Parameters

pStore

Vedis datastore handle.

Return value

Random generated number and/or string.
