C语言实现字符转unix时间戳的简单实例

#include 
#include 
int strtotime(char datetime[])
{
struct tm tm_time;
int unixtime;
strptime(datetime, "%Y-%m-%d %H:%M:%S", &tm_time);

unixtime = mktime(&tm_time);
return unixtime;
}


另附上几个时间相关的函数，做个笔记：

//当前时间


char* get_curr_time()
{
char* strtime = (char *)malloc(sizeof(char)*20);
memset(strtime, 0, sizeof(char)*20);
time_t now;
time(&now);
strftime(strtime, 20, "%Y-%m-%d %H:%M:%S", gmtime(&now));
printf("Info: current time %s\n", strtime);
return strtime;
}


//当前时间的unix时间戳


int get_curr_unixtime(void)
{
time_t now;
int unixtime = time(&now);
return unixtime;
}


//字符转unix时间戳


int strtotime(char datetime[])
{
struct tm tm_time;
int unixtime;
strptime(datetime, “%Y-%m-%d %H:%M:%S”, &tm_time);

unixtime = mktime(&tm_time);
return unixtime;
}
