OPENSSL_FILE(3) OpenSSL OPENSSL_FILE(3) NAME OPENSSL_FILE, OPENSSL_LINE, OPENSSL_FUNC, OPENSSL_MSTR, OPENSSL_MSTR_HELPER - generic C programming utility macros LIBRARY libcrypto, -lcrypto 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 see above SEE ALSO crypto(7) HISTORY OPENSSL_FUNC, OPENSSL_MSTR, and OPENSSL_MSTR_HELPER were added in OpenSSL 3.0.
