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.
