    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);
          char *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.

    HISTORY

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