They can still be useful for anyone that wants to make their own macros.</p> <p>ERR_new() allocates a new slot in the thread's error queue.</p> <p>ERR_set_debug() sets the debug information related to the current error in the thread's error queue. The values that can be given are the filename <i>file</i>, line in the file <i>line</i> and the name of the function <i>func</i> where the error occurred. The names must be constant, this function will only save away the pointers, not copy the strings.</p> <p>ERR_set_error() sets the error information, which are the library number <i>lib</i> and the reason code <i>reason</i>, and additional data as a format string <i>fmt</i> and an arbitrary number of arguments. The additional data is processed with <a href="../man3/BIO_snprintf.html">BIO_snprintf(3)</a> to form the additional data string, which is allocated and store in the error record.</p> <p>ERR_vset_error() works like ERR_set_error(), but takes a <b>va_list</b> argument instead of a variable number of arguments.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>ERR_new, ERR_set_debug, ERR_set_error and ERR_vset_error do not return any values.</p> <h1 id="NOTES">NOTES</h1> <p>The library number is unique to each unit that records errors. OpenSSL has a number of preallocated ones for its own uses, but others may allocate their own library number dynamically with <a href="../man3/ERR_get_next_error_library.html">ERR_get_next_error_library(3)</a>.</p> <p>Reason codes are unique within each library, and may have an associated set of strings as a short description of the reason. For dynamically allocated library numbers, reason strings are recorded with <a href="../man3/ERR_load_strings.html">ERR_load_strings(3)</a>.</p> <p>Provider authors are supplied with core versions of these functions, see <a href="../man7/provider-base.html">provider-base(7)</a>.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/ERR_raise.html">ERR_raise(3)</a>, <a href="../man3/ERR_get_next_error_library.html">ERR_get_next_error_library(3)</a>, <a href="../man3/ERR_load_strings.html">ERR_load_strings(3)</a>, <a href="../man3/BIO_snprintf.html">BIO_snprintf(3)</a>, <a href="../man7/provider-base.html">provider-base(7)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2020 The OpenSSL Project Authors.
