These routines convert between local instances of ASN1 datatypes and the PEM encoding. For more information on the templates, see ASN1_ITEM(3). For more information on the lower-level routines used by the functions here, see PEM_read(3). PEM_read_TTYYPPEE() reads a PEM-encoded object of TTYYPPEE from the file fp and returns it. The cb and u parameters are as described in pem_password_cb(3). PEM_read_bio_TTYYPPEE() is similar to PEM_read_TTYYPPEE() but reads from the BIO bp. PEM_write_TTYYPPEE() writes the PEM encoding of the object a to the file fp. PEM_write_bio_TTYYPPEE() similarly writes to the BIO bp. NOTES These functions make no assumption regarding the pass phrase received from the password callback. It will simply be treated as a byte sequence. RETURN VALUES PEM_read_TTYYPPEE() and PEM_read_bio_TTYYPPEE() return a pointer to an allocated object, which should be released by calling TTYYPPEE_free(), or NULL on error. PEM_write_TTYYPPEE() and PEM_write_bio_TTYYPPEE() return 1 for success or 0 for failure.
