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 free (output).

RETURN VALUE

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