.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "PEM_READ_CMS 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.

The macro DECLARE_PEM_rw expands to the set of declarations shown in the next four lines of the synopsis.

These routines convert between local instances of \s-1ASN1\s0 datatypes and the \s-1PEM\s0 encoding. For more information on the templates, see \s-1ASN1_ITEM\s0\|(3). For more information on the lower-level routines used by the functions here, see PEM_read\|(3).

\fBPEM_read_TYPE() reads a PEM-encoded object of \s-1TYPE\s0 from the file fp and returns it. The cb and u parameters are as described in \fBpem_password_cb\|(3).

\fBPEM_read_bio_TYPE() is similar to PEM_read_TYPE() but reads from the \s-1BIO\s0 bp.

\fBPEM_write_TYPE() writes the \s-1PEM\s0 encoding of the object a to the file fp.

\fBPEM_write_bio_TYPE() similarly writes to the \s-1BIO\s0 bp.

Header "NOTES" These functions make no assumption regarding the pass phrase received from the password callback. It will simply be treated as a byte sequence. Header "RETURN VALUES" \fBPEM_read_TYPE() and PEM_read_bio_TYPE() return a pointer to an allocated object, which should be released by calling TYPE_free(), or \s-1NULL\s0 on error.

\fBPEM_write_TYPE() and PEM_write_bio_TYPE() return the number of bytes written or zero on error.
