you can find this sort of information in the manual pages, either on you UNIX*SH operating system,
or online on our website:


The read routines return either a pointer to the structure read or NULL if an error occurred.

d2i_TYPE(), d2i_TYPE_bio() and d2i_TYPE_fp() return a valid TYPE structure or NULL if an error occurs. If the "reuse" capability has been used with a valid structure being passed in via a, then the object is freed in the event of error and *a is set to NULL.
i2d_TYPE() returns the number of bytes successfully encoded or a negative value if an error occurs.
i2d_TYPE_bio() and i2d_TYPE_fp() return 1 for success and 0 if an error occurs.

Hi ,

I have two queries to be asked.

  1.  Is there any Api which is used to convert certificates from PEM format to DER format?
  2.  Does these two Api's return same value ?( These Api's give NULL when they are failing, I need to know if they return same value in success case)
  3.  d2i_X509_bio
  4.  PEM_read_bio_X509
