ERR_load_crypto_strings(3) OpenSSL ERR_load_crypto_strings(3)NAME
ERR_load_crypto_strings, SSL_load_error_strings, ERR_free_strings - load and free error strings
ERR_load_crypto_strings() registers the error strings for all libcrypto functions. SSL_load_error_strings() does the same, but also
registers the libssl error strings.
One of these functions should be called before generating textual error messages. However, this is not required when memory usage is an
ERR_free_strings() frees all previously loaded error strings.
ERR_load_crypto_strings(), SSL_load_error_strings() and ERR_free_strings() return no values.
SEE ALSO err(3), ERR_error_string(3)HISTORY
ERR_load_error_strings(), SSL_load_error_strings() and ERR_free_strings() are available in all versions of SSLeay and OpenSSL.

ERR_error_string, ERR_error_string_n, ERR_lib_error_string, ERR_func_error_string, ERR_reason_error_string - obtain human-readable error
char *ERR_error_string(unsigned long e, char *buf);
void ERR_error_string_n(unsigned long e, char *buf, size_t len);
const char *ERR_lib_error_string(unsigned long e);
const char *ERR_func_error_string(unsigned long e);
const char *ERR_reason_error_string(unsigned long e);
ERR_error_string() generates a human-readable string representing the error code e, and places it at buf. buf must be at least 120 bytes
long. If buf is NULL, the error string is placed in a static buffer. ERR_error_string_n() is a variant of ERR_error_string() that writes
at most len characters (including the terminating 0) and truncates the string if necessary. For ERR_error_string_n(), buf may not be NULL.
The string will have the following format:
error:[error code]:[library name]:[function name]:[reason string]
error code is an 8 digit hexadecimal number, library name, function name and reason string are ASCII text.
ERR_lib_error_string(), ERR_func_error_string() and ERR_reason_error_string() return the library name, function name and reason string
The OpenSSL error strings should be loaded by calling ERR_load_crypto_strings(3) or, for SSL applications, SSL_load_error_strings(3) first.
If there is no text string registered for the given error code, the error string will contain the numeric code.
ERR_print_errors(3) can be used to print all error codes currently in the queue.
ERR_error_string() returns a pointer to a static buffer containing the string if buf == NULL, buf otherwise.
ERR_lib_error_string(), ERR_func_error_string() and ERR_reason_error_string() return the strings, and NULL if none is registered for the

ERR_error_string() is available in all versions of SSLeay and OpenSSL. ERR_error_string_n() was added in OpenSSL 0.9.6.
