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.
