C++ PKIX_ERROR函数代码示例

/*
 * FUNCTION: pkix_List_GetElement
 * DESCRIPTION:
 *
 *  Copies the "list"'s element at "index" into "element". The input List must
 *  be the header of the List (as opposed to being an element of the List). The
 *  index counts from zero and must be less than the List's length. This
 *  function does NOT increment the reference count of the List element since
 *  the returned element's reference will not be stored by the calling
 *  function.
 *
 * PARAMETERS:
 *  "list"
 *      Address of List (must be header) to get element from. Must be non-NULL.
 *  "index"
 *      Index of list to get element from. Must be less than List's length.
 *  "pElement"
 *      Address where object pointer will be stored. Must be non-NULL.
 *  "plContext"
 *      Platform-specific context pointer.
 * THREAD SAFETY:
 *  Conditionally Thread Safe
 *      (see Thread Safety Definitions in Programmer's Guide)
 * RETURNS:
 *  Returns NULL if the function succeeds.
 *  Returns a Fatal Error if the function fails in an unrecoverable way.

/*
 * FUNCTION: pkix_pl_CRL_GetVersion
 * DESCRIPTION:
 *
 *  Retrieves the version of the CRL pointed to by "crl" and stores it at
 *  "pVersion". The version number will either be 0 or 1 (corresponding to
 *  v1 or v2, respectively).
 *
 *  Version  ::=  INTEGER  {  v1(0), v2(1), v3(2)  }
 *
 * PARAMETERS:
 *  "crl"
 *      Address of CRL whose version is to be stored. Must be non-NULL.
 *  "pVersion"
 *      Address where a version will be stored. Must be non-NULL.
 *  "plContext"
 *      Platform-specific context pointer.
 * THREAD SAFETY:
 *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
 * RETURNS:
 *  Returns NULL if the function succeeds.
 *  Returns a CRL Error if the function fails in a non-fatal way.
 *  Returns a Fatal Error if the function fails in an unrecoverable way.
