我试图在包含日期信息的事件结构中重复添加一个星期。我这样做是为了在某个时间之前创建一个事件的多个实例。我的mktime函数有一个seg错误,其中full_time = mktime(&caltime);我不知道原因。
void multiple(icalevent event, int is_location){
icalevent temp;
int rrule_bound = atoi(event.rrule);
int rtime_bound = atoi(event.rtime);
int start_bound = atoi(event.start);
int stime_bound = atoi(event.stime);
char buffer[9];
struct tm caltime;
time_t full_time;
char time_str[15];
temp = cpystruct(event, is_location);
while((start_bound <= rrule_bound) && (stime_bound <= rtime_bound)){
memset(&caltime, 0, sizeof(struct tm));
strncpy(time_str, temp.start, 9);
strncat(time_str, temp.stime, 6);
strptime(time_str, "%Y%m%d%H%M%S", &caltime);
caltime.tm_mday += 7;
full_time = mktime(&caltime);
if(caltime.tm_isdst == 1){
caltime.tm_hour -= 1;
}
full_time = mktime(&caltime);
strftime(buffer, 9, "%Y%m%d", &caltime);
start_bound = atoi(buffer);
strncpy(temp.end, buffer, 8);
strncpy(temp.start, buffer, 8);
if((start_bound <= rrule_bound) && (stime_bound <= rtime_bound)){
/*create a sort string*/
calendar[percent_full] = cpystruct(temp, is_location);
printst(calendar[percent_full]);
percent_full++;
}
else{
break;
}
}
return;
}icalevent结构:
typedef struct{
char start[9]; /*"YYYYMMDD*/
char stime[7]; /*"HHMMSS"*/
char end[9]; /*"YYYYMMDD"*/
char etime[7]; /*"HHMMSS"*/
char rrule[9]; /*"YYYYMMDD"*/
char rtime[7]; /*"HHMMSS"*/
char *location; /*"2343 fake street"*/
char *summary; /*"Halloween party"*/
char *sort_str; /*"YYYYMMDDHHMMSSHalloween party*/
} icalevent编辑
icalevent cpystruct(icalevent temp, int is_location) {
icalevent perm;
strncpy(perm.start, temp.start, 9);
strncpy(perm.stime, temp.stime, 7);
strncpy(perm.end, temp.end, 9);
strncpy(perm.etime, temp.etime, 7);
strncpy(perm.rrule, temp.rrule, 9);
strncpy(perm.rtime, temp.rtime, 7);
if(is_location) {
perm.location = strdup(temp.location);
} else {
perm.location = NULL;
}
perm.summary = strdup(temp.summary);
perm.sort_str = strdup(temp.sort_str);
return perm;

很可能,您的问题不是mktime,而是您的复制语句之一。第一个是
strncat(time_str, temp.stime, 6);有了这个time_str,很可能不会终止NUL。
这里也一样
strncpy(temp.end, buffer, 8);
strncpy(temp.start, buffer, 8);temp.end和temp.start可能在以前被终止,但你不能确定。只需使用strcpy即可。
下一个是
calendar[percent_full] = cpystruct(temp, is_location);
printst(calendar[percent_full]);
percent_full++;我没有看到calendar结束时的支票。因此,在日历结束后可能会有一段文字。
作为旁白,当你做的时候
if(caltime.tm_isdst == 1){
caltime.tm_hour -= 1;
}tm_hour可能成为阴性。
