[openssl-dev] Cannot find the function int (*get_issuer)(X509 **issuer, X509_STORE_CTX *ctx, X509 *x)

[陈雨亭]

Hello, can anyone help me to find where the function get_issuer (...) is 
defined?
Sorry for the naïve question.

The function is referred in crypto/x509/x509_vfy.c
290  /* If we are self signed, we break */
291  if (ctx->check_issued(ctx,x,x)) break;
292
293   ok = ctx->get_issuer(&xtmp, ctx, x);
294   295  if (ok < 0) return ok;
296   if (ok == 0) break;
297   ...
306  }
