# NAME

X509_STORE_CTX_get_by_subject, X509_STORE_CTX_get_obj_by_subject - X509 and X509_CRL lookup functions

# SYNOPSIS

    #include <openssl/x509_vfy.h>

    int X509_STORE_CTX_get_by_subject(const X509_STORE_CTX *vs,
                                      X509_LOOKUP_TYPE type,
                                      const X509_NAME *name, X509_OBJECT *ret);
    X509_OBJECT *X509_STORE_CTX_get_obj_by_subject(X509_STORE_CTX *vs,
                                                   X509_LOOKUP_TYPE type,
                                                   const X509_NAME *name);

# DESCRIPTION

X509_STORE_CTX_get_by_subject() tries to find an object of given type, which may be X509_LU_X509 or X509_LU_CRL, and subject name from the store in the provided store context vs. If found and ret is not NULL, it increments the reference count and stores the looked up object in ret.

X509_STORE_CTX_get_obj_by_subject() is like X509_STORE_CTX_get_by_subject() but returns the found object on success, else NULL.

# RETURN VALUES

X509_STORE_CTX_get_by_subject() returns 1 if the lookup was successful, else 0.

X509_STORE_CTX_get_obj_by_subject() returns an object on success, else NULL.
