ERR_put_error(3)                    OpenSSL                   ERR_put_error(3)



NAME
       ERR_put_error, ERR_add_error_data, ERR_add_error_vdata - record an
       error

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/err.h>

        void ERR_put_error(int lib, int func, int reason, const char *file, int line);

        void ERR_add_error_data(int num, ...);
        void ERR_add_error_vdata(int num, va_list arg);

DESCRIPTION
       ERR_put_error() adds an error code to the thread's error queue. It
       signals that the error of reason code reason occurred in function func
       of library lib, in line number line of file.  This function is usually
       called by a macro.

       ERR_add_error_data() associates the concatenation of its num string
       arguments with the error code added last.  ERR_add_error_vdata() is
       similar except the argument is a va_list.

       ERR_load_strings(3) can be used to register error strings so that the
       application can a generate human-readable error messages for the error
       code.

   Reporting errors
       Each sub-library has a specific macro XXXerr() that is used to report
       errors. Its first argument is a function code XXX_F_..., the second
       argument is a reason code XXX_R_.... Function codes are derived from
       the function names; reason codes consist of textual error descriptions.
       For example, the function ssl3_read_bytes() reports a "handshake
       failure" as follows:

        SSLerr(SSL_F_SSL3_READ_BYTES, SSL_R_SSL_HANDSHAKE_FAILURE);

       Function and reason codes should consist of upper case characters,
       numbers and underscores only. The error file generation script
       translates function codes into function names by looking in the header
       files for an appropriate function name, if none is found it just uses
       the capitalized form such as "SSL3_READ_BYTES" in the above example.

       The trailing section of a reason code (after the "_R_") is translated
       into lower case and underscores changed to spaces.

       Although a library will normally report errors using its own specific
       XXXerr macro, another library's macro can be used. This is normally
       only done when a library wants to include ASN1 code which must use the
       ASN1err() macro.

RETURN VALUES
       ERR_put_error() and ERR_add_error_data() return no values.
