◆ OXR_TWO_CALL_CHECK_GOTO

#define OXR_TWO_CALL_CHECK_GOTO (   log,
  cnt_input,

Value:

goto goto_label; \
} \
*(cnt_output) = (uint32_t)(count); \
\

goto goto_label; \
} \
} while (false)

◆ OXR_TWO_CALL_CHECK_ONLY

#define OXR_TWO_CALL_CHECK_ONLY (   log,
  cnt_input,
  cnt_output,
  count,
  sval 
)
Value:
do { \
if ((cnt_output) == NULL) { \
return oxr_error(log, XR_ERROR_VALIDATION_FAILURE, #cnt_output); \
} \
*(cnt_output) = (uint32_t)(count); \
\

  goto_label 
)
Value:
do { \

\
for (uint32_t i = 0; i < count; i++) { \

} \
return sval; \
} while (false)

Calls fill_fn(&output_struct[i], &source_struct[i]) to fill output_structs.

  cnt_input,
  cnt_output,
  output,
  count,

\
for (uint32_t i = 0; i < (count); i++) { \
(output)[i] = (data)[i]; \
} \
return (sval); \
} while (false)
