API 概述

OSSL_CMP_try_certreq 是 openssl 中的一个API。该规属于return value check 类型。该规则是使用 AURC 生成的。

规则描述

提示

OSSL_CMP_try_certreq() returns 1 if the requested certificate is available via L<OSSL_CMP_CTX_get0_newCert(3)> or on successfully aborting a pending certificate request, 0 on error, and -1 in case a 'waiting' status has been received and checkAfter value is available. In the latter case L<OSSL_CMP_CTX_get0_newCert(3)> yields NULL and the output parameter I<checkAfter> has been used to assign the received value unless I<checkAfter> is NULL.
