NAME

       gsasl_step - API function

SYNOPSIS

       #include <gsasl.h>

       int gsasl_step(Gsasl_session * sctx, const char * input, size_t input_len, char ** output,
       size_t * output_len);

ARGUMENTS

       Gsasl_session * sctx
                   libgsasl session handle.

       const char * input
                   input byte array.

       size_t input_len
                   size of input byte array.

       char ** output
                   newly allocated output byte array.

       size_t * output_len
                   pointer to output variable with size of output byte array.

DESCRIPTION

       Perform one step of SASL authentication.  This reads data from the other end (from   input
       and   input_len  ),  processes it (potentially invoking callbacks to the application), and
       writes data to server (into newly allocated variable  output and  output_len that indicate
       the length of  output ).

       The contents of the  output buffer is unspecified if this functions returns anything other
       than GSASL_OK or GSASL_NEEDS_MORE.  If this function return GSASL_OK or  GSASL_NEEDS_MORE,
       however, the
        output  buffer  is  allocated by this function, and it is the responsibility of caller to
       deallocate it by calling gsasl_free( output ).

       Return value: Returns GSASL_OK if authenticated terminated successfully,  GSASL_NEEDS_MORE
       if more data is needed, or error code.
