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.
