Vars_MoveNext

Env::Vars_MoveNext

uint8_t Vars_MoveNext(uint32_t iSlot , void* pKey , uint32_t& nKey , void* pVal , uint32_t& nVal , uint8_t nRepeat);

Reads the next variable specified by iSlot

Parameters

• iSlot : enumeration slot returned by Vars_Enum
• pKey : pointer to the key buffer
• nKey : the size of the key buffer
• pVal : pointer to the value buffer
• nVal : the size of the value buffer
• nRepeat : 1 - don't move read current variable again, 0 - read next variable

Return value

• 1 if successful
• 0 otherwise

Notes

• the slot number should be obtained with Vars_Enum function
• this function copies nKey bytes to pKey and then overrides nKey with exact size of the key
• this function copies nVal bytes to pVal and then overrides nVal with exact size of the value
