ERR_new, ERR_set_debug, ERR_set_error, ERR_vset_error - Error recording building blocks
#include <openssl/err.h>
void ERR_new(void);
void ERR_set_debug(const char *file, int line, const char *func);
void ERR_set_error(int lib, int reason, const char *fmt, ...);
void ERR_vset_error(int lib, int reason, const char *fmt, va_list args);The functions described here are generally not used directly, but rather through macros such as BIO_snprintf(3) to form the additional data string, which is allocated and store in the error record.
ERR_vset_error() works like ERR_set_error(), but takes a va_list argument instead of a variable number of arguments.
ERR_new, ERR_set_debug, ERR_set_error and ERR_vset_error do not return any values.
The library number is unique to each unit that records errors. OpenSSL has a number of pre-allocated ones for its own uses, but others may allocate their own library number dynamically with ERR_load_strings(3).
Provider authors are supplied with core versions of these functions, see SEE ALSO
