Env::Vars_Enum

uint32_t Vars_Enum(const void* pKey0 , uint32_t nKey0 , const void* pKey1 , uint32_t nKey1);

Starts variable enumeration process in key range [key0, key1]

Parameters

• pKey0 : pointer to the lower bound key buffer
• nKey0 : the size of the lower bound key buffer
• pKey1 : pointer to the upper bound key buffer
• nKey1 : the size of the upper bound key buffer

Return value

• the slot number which could be used to work with this enumeration

Notes

• the slot number should be used with Vars_MoveNext and Vars_Close functions
