VarGetProof

Env::VarGetProof

uint32_t VarGetProof(const void* pKey , uint32_t nKey ,
                     const void** ppVal , uint32_t* pnVal , const Merkle::Node** ppProof);

Gets Merkle proof for the variable with given key

Parameters

• pKey : pointer to the key buffer
• nKey : the size of the key buffer
• ppVal: pointer to the address of the value buffer
• pnVal: pointer to the address of the value buffer size
• ppProof: pointer to the address of the Merkle proof buffer

Return value

• the number of nodes in the Merkle proof

Notes

• none
