.. 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 turned on, 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'.

For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
"NAME"
ERR_load_strings, ERR_PACK, ERR_get_next_error_library - load arbitrary error strings
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1 #include <openssl/err.h> \& void ERR_load_strings(int lib, ERR_STRING_DATA str[]); \& int ERR_get_next_error_library(void); \& unsigned long ERR_PACK(int lib, int func, int reason); .Ve
"DESCRIPTION"
Header "DESCRIPTION" \fIERR_load_strings() registers error strings for library number lib.

\fBstr is an array of error string data:

.Vb 5 typedef struct ERR_string_data_st { unsigned long error; char *string; } ERR_STRING_DATA; .Ve

The error code is generated from the library number and a function and reason code: error = \s-1ERR_PACK\s0(lib, func, reason). \s-1ERR_PACK\s0() is a macro.

The last entry in the array is {0,0}.

\fIERR_get_next_error_library() can be used to assign library numbers to user libraries at runtime.

"RETURN VALUE"
Header "RETURN VALUE" \fIERR_load_strings() returns no value. \s-1ERR_PACK\s0() return the error code. \fIERR_get_next_error_library() returns a new library number.
"SEE ALSO"
Header "SEE ALSO" \fIerr\|(3), ERR_load_strings\|(3)
"HISTORY"
Header "HISTORY" \fIERR_load_error_strings() and \s-1ERR_PACK\s0() are available in all versions of SSLeay and OpenSSL. ERR_get_next_error_library() was added in SSLeay 0.9.0.
