ssl_load_error_strings(3) [redhat man page]

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 SYNOPSIS
#include <openssl/err.h> void ERR_load_crypto_strings(void); void ERR_free_strings(void); #include <openssl/ssl.h> void SSL_load_error_strings(void); DESCRIPTION
ERR_load_crypto_strings() registers the error strings for all libcrypto functions. SSL_load_error_strings() does the same, but also regis- ters 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 issue. ERR_free_strings() frees all previously loaded error strings. RETURN VALUES
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. 0.9.7a 2000-02-24 ERR_load_crypto_strings(3)

NAME
ERR_error_string, ERR_error_string_n, ERR_lib_error_string, ERR_func_error_string, ERR_reason_error_string - obtain human-readable error message SYNOPSIS
#include <openssl/err.h> 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); DESCRIPTION
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 respectively. 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. RETURN VALUES
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 error code. SEE ALSO
err(3), ERR_get_error(3), ERR_load_crypto_strings(3), SSL_load_error_strings(3) ERR_print_errors(3) HISTORY
ERR_error_string() is available in all versions of SSLeay and OpenSSL. ERR_error_string_n() was added in OpenSSL 0.9.6. 1.0.1e 2013-02-11 ERR_error_string(3)
