Macro Definition Documentation

#define LOG_INDEX_ADD_SECT_PTR	(		sect,
			ptr
	)

Value:

{slidx_list_t *hl = &slidx_pool.buffer[slidx_pool.cur_idx]; \
    hl->hdr = ptr; \
    list_add(&hl->list, &(sect)); \
    slidx_pool.cur_idx = (slidx_pool.cur_idx + 1)%slidx_pool.max_idx; }

mca_make_slidx - Make index of SAL error record : pointer to SAL error record : pointer to index of SAL error record

Return value: 1 if record has platform error / 0 if not
