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.
