OPENSSL_FILE(3ossl) OpenSSL OPENSSL_FILE(3ossl)
NAME
OPENSSL_FILE, OPENSSL_LINE, OPENSSL_FUNC, OPENSSL_MSTR,
OPENSSL_MSTR_HELPER - generic C programming utility macros
SYNOPSIS
#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)
DESCRIPTION
The macros OPENSSL_FILE and OPENSSL_LINE typically yield the current
filename and line number during C compilation. When
OPENSSL_NO_FILENAMES is defined they yield "" and 0, respectively.
The macro OPENSSL_FUNC attempts to yield the name of the C function
currently being compiled, as far as language and compiler versions
allow. Otherwise, it yields "(unknown function)".
The macro OPENSSL_MSTR yields the expansion of the macro given as
argument, which is useful for concatenation with string constants. The
macro OPENSSL_MSTR_HELPER is an auxiliary macro for this purpose.
RETURN VALUES
