C_GetMechanismList() публичный Метод

Obtains a list of mechanism types supported by a token
public C_GetMechanismList ( ulong slotId, CKM mechanismList, ulong &count ) : CKR
slotId ulong The ID of the token's slot
mechanismList CKM /// If set to null then the number of mechanisms is returned in "count" parameter, without actually returning a list of mechanisms. /// If not set to null then "count" parameter must contain the lenght of mechanismList array and mechanism list is returned in "mechanismList" parameter. ///
count ulong Location that receives the number of mechanisms
Результат CKR
