您如何在CRL_DIST_POINT结构中默认字段? [英] How do you default fields in the CRL_DIST_POINT structure?
问题描述
http: //msdn.microsoft.com/zh-CN/library/windows/desktop/aa379874(v=vs.85).aspx
定义
typedef struct _CRL_DIST_POINT {
CRL_DIST_POINT_NAME DistPointName;
CRYPT_BIT_BLOB ReasonFlags;
CERT_ALT_NAME_INFO CRLIssuer;
} CRL_DIST_POINT
typedef struct _CRL_DIST_POINT {
CRL_DIST_POINT_NAME DistPointName;
CRYPT_BIT_BLOB ReasonFlags;
CERT_ALT_NAME_INFO CRLIssuer;
} CRL_DIST_POINT
并说:
A CRL_DIST_POINT_NAME 结构，用于标识CRL源的位置.如果 NULL ，分发点名称默认为 CRLIssuer 名称.
A CRL_DIST_POINT_NAME structure that identifies the location of a CRL source. If NULL, the distribution point name defaults to the CRLIssuer name.
A CRYPT_BIT_BLOB ，其中包含一个字节，用于指示CRL所涵盖的吊销原因.
A CRYPT_BIT_BLOB that contains a byte that indicates the revocation reasons covered by the CRL.
如果 NULL ，则指示的CRL分发点将分发一个CRL，如果该证书已被吊销，则将包含该证书的条目，而不考虑吊销原因.
If NULL, the indicated CRL distribution point distributes a CRL that will contain an entry for this certificate if this certificate has been revoked, regardless of the revocation reason.
我该如何编写代码以使 DistPointName和ReasonFlags为NULL?
How would I write code to make DistPointName and ReasonFlags NULL ?
CRL_DIST_POINT crlPoint;
crlPoint.ReasonFlags = NULL;
crlPoint.CRLIssuer = NULL;
出现以下错误:
1> c:\ users \ andrew \ src2011 \ c ++ \ win32 \ io \ httpcrypto.cpp(441):错误C2679:二进制'=' (或没有可接受的转化)
1>c:\users\andrew\src2011\c++\win32\io\httpcrypto.cpp(441): error C2679: binary '=' : no operator found which takes a right-hand operand of type 'int' (or there is no acceptable conversion)

谢谢.

defines
typedef struct _CRL_DIST_POINT {
CRL_DIST_POINT_NAME DistPointName;

structure that identifies the location of a CRL source. If*NULL*, the
distribution point name defaults to the *CRLIssuer* name.
我怀疑文档为NULL表示其dwDistPointNameChoice成员设置为CRL_DIST_POINT_NO_NAME.
I suspect that by NULL the doc means that its dwDistPointNameChoice member is set to CRL_DIST_POINT_NO_NAME.
* ReasonFlags *
A
* CRYPT_BIT_BLOB *< http://msdn.microsoft.com/zh-我们/library/windows/desktop/aa381165 (v = vs.85).aspx>
包含一个字节，该字节指示
所涵盖的吊销原因 CRL.
如果为* NULL *，则指示的CRL分发点分发CRL
如果该证书将包含该证书的条目
无论吊销原因如何，都已被吊销.
*ReasonFlags*
A
*CRYPT_BIT_BLOB*<http://msdn.microsoft.com/en-us/library/windows/desktop/aa381165(v=vs.85).aspx>
that contains a byte that indicates the revocation reasons covered by
the CRL.
If *NULL*, the indicated CRL distribution point distributes a CRL
that will contain an entry for this certificate if this certificate
has been revoked, regardless of the revocation reason.
这里NULL可能意味着CRYPT_BIT_BLOB的所有三个字段都设置为0或NULL.
And here NULL likely means that all three fields of CRYPT_BIT_BLOB are set to 0 or NULL.
