NAME

6       OPENSSL_FILE, OPENSSL_LINE, OPENSSL_FUNC, OPENSSL_MSTR,
7       OPENSSL_MSTR_HELPER - generic C programming utility macros
8

SYNOPSIS

10        #include <openssl/macros.h>
11
12        #define OPENSSL_FILE /* typically: __FILE__ */
13        #define OPENSSL_LINE /* typically: __LINE__ */
14        #define OPENSSL_FUNC /* typically: __func__ */
15
16        #define OPENSSL_MSTR_HELPER(x) #x
17        #define OPENSSL_MSTR(x) OPENSSL_MSTR_HELPER(x)

DESCRIPTION

20       The macros OPENSSL_FILE and OPENSSL_LINE typically yield the current
21       filename and line number during C compilation.  When
22       OPENSSL_NO_FILENAMES is defined they yield "" and 0, respectively.
23
24       The macro OPENSSL_FUNC attempts to yield the name of the C function
25       currently being compiled, as far as language and compiler versions
26       allow.  Otherwise, it yields "(unknown function)".
27
28       The macro OPENSSL_MSTR yields the expansion of the macro given as
29       argument, which is useful for concatenation with string constants.  The
30       macro OPENSSL_MSTR_HELPER is an auxiliary macro for this purpose.
