similar to stats.c: In function 'init_collector_data': stats.c:196:2: warning: call to function 'zbx_procstat_init' without a real prototype [-Wunprototyped-calls] zbx_procstat_init(&collector->procstat); ^ In file included from stats.h:38:0, from stats.c:21: procstat.h:49:6: note: 'zbx_procstat_init' was declared here void zbx_procstat_init(); ^ stats.c: In function 'free_collector_data': stats.c:232:2: warning: call to function 'zbx_procstat_destroy' without a real prototype [-Wunprototyped-calls] zbx_procstat_destroy(&collector->procstat); ^ In file included from stats.h:38:0, from stats.c:21: procstat.h:50:6: note: 'zbx_procstat_destroy' was declared here void zbx_procstat_destroy(); ^ stats.c: In function 'init_collector_data': stats.c:196:2: warning: call to function 'zbx_procstat_init' without a real prototype [-Wunprototyped-calls] zbx_procstat_init(&collector->procstat); ^ In file included from stats.h:38:0, from stats.c:21: procstat.h:49:6: note: 'zbx_procstat_init' was declared here void zbx_procstat_init(); ^ stats.c: In function 'free_collector_data': stats.c:232:2: warning: call to function 'zbx_procstat_destroy' without a real prototype [-Wunprototyped-calls] zbx_procstat_destroy(&collector->procstat); ^ In file included from stats.h:38:0, from stats.c:21: procstat.h:50:6: note: 'zbx_procstat_destroy' was declared here void zbx_procstat_destroy(); ^ it also looks like stats.c is compiled twice - once for agent, once for agentd. we might want to ignore that until agent is removed for 3.2 |

(1) Since neither zbx_procstat_init() nor zbx_procstat_destroy() use the passed parameter I suggest to fix this issue by removing the parameter from both definition and declaration. viktors.tjarve RESOLVED in r56890. sandis.neilands CLOSED. |

(2) In order to avoid warnings like these in the future, it might be better to add "void" to parameter-less functions in procstat.c, like this: Index: src/zabbix_agent/procstat.c =================================================================== --- src/zabbix_agent/procstat.c (revision 56928) +++ src/zabbix_agent/procstat.c (working copy) @@ -987,7 +987,7 @@ * Return value: This function calls exit() on shared memory errors. * * * ******************************************************************************/ -void zbx_procstat_init() +void zbx_procstat_init(void) { char *errmsg = NULL; This prevents programmers from passing arguments to that function. Otherwise, zbx_procstat_init() can be legally given any number of arguments. viktors.tjarve RESOLVED directly in trunk in r56931. asaveljevs Looks good. CLOSED. |
