I have a lib.h
file, inside which I use the function gettimeofday
:
struct timeval tn;
struct tm *time;
gettimeofday(&tn, NULL);
time = gmtime(&tn.tv_sec);
I included the library time.h
:
#include <time.h>
And the function works perfectly, I can correctly print the time of the day. Then why is this warning happening?
In file included from main.c:1:
lib.h: In function ‘execute_remote_script’:
lib.h:86:5: warning: implicit declaration of function ‘gettimeofday’ [-Wimplicit-function-declaration]
86 | gettimeofday(&tn, NULL);
In main.c
:
#include "lib.h"
add #include <sys/time.h>
