.. 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 "OPENSSL_FILE 3ossl" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
OPENSSL_FILE, OPENSSL_LINE, OPENSSL_FUNC, OPENSSL_MSTR, OPENSSL_MSTR_HELPER \- generic C programming utility macros Header "SYNOPSIS" .Vb 1 #include <openssl/macros.h> \& #define OPENSSL_FILE /* typically: _\|_FILE_\|_ */ #define OPENSSL_LINE /* typically: _\|_LINE_\|_ */ #define OPENSSL_FUNC /* typically: _\|_func_\|_ */ \& #define OPENSSL_MSTR_HELPER(x) #x #define OPENSSL_MSTR(x) OPENSSL_MSTR_HELPER(x) .Ve Header "DESCRIPTION" The macros \s-1OPENSSL_FILE\s0 and \s-1OPENSSL_LINE\s0 typically yield the current filename and line number during C compilation. When \s-1OPENSSL_NO_FILENAMES\s0 is defined they yield "" and 0, respectively.

The macro \s-1OPENSSL_FUNC\s0 attempts to yield the name of the C function currently being compiled, as far as language and compiler versions allow. Otherwise, it yields \*(L"(unknown function)\*(R".

The macro \s-1OPENSSL_MSTR\s0 yields the expansion of the macro given as argument, which is useful for concatenation with string constants. The macro \s-1OPENSSL_MSTR_HELPER\s0 is an auxiliary macro for this purpose.

Header "RETURN VALUES" see above Header "SEE ALSO" \fBcrypto\|(7) Header "HISTORY" \fB\s-1OPENSSL_FUNC\s0, \s-1OPENSSL_MSTR\s0, and \s-1OPENSSL_MSTR_HELPER\s0 were added in OpenSSL 3.0. Header "COPYRIGHT" Copyright 2018-2019 The OpenSSL Project Authors. All Rights Reserved.
