gsasl_step − API function
#include <gsasl.h>
int gsasl_step(Gsasl_session * sctx, const char * input, size_t input_len, char ** output, size_t * output_len);
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.
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.
