@veficos how?😊
veficos
void gettime(char* buffer){
struct timeval time_now;
char ms[7];
gettimeofday(&time_now, NULL);
struct tm *time_str_tm = gmtime(&time_now.tv_sec);
strftime (buffer, 256, "%d.%m.%Y %H:%m:%S", time_str_tm);
sprintf(ms, ":%06ld", time_now.tv_usec);
strcat(buffer, ms);
}

Hi
Volad Malevich
help again pls)
Volad Malevich
i need to get result of system("ps -A") to variable
Volad Malevich
is it possible?
veficos
u can use pipe to receive result..
Joe
please help. I included a header file in my project and everything compiles without a problem, but when using the functions from the header file it says undefined reference to (function)
Volad Malevich
please help me to get result of system("ps -A") to variable via PIPE or other way. I found some in google, but it's not exactly what i need.
Volad Malevich
?
veficos
like:
int pid;
int fds[2];
pipe(fds);
pid = fork();
if(pid == 0){
close(1);
dup2(fds[1], 1);
close(fds[0]);
execlp("ps", "ps", "-a", NULL);
} else {
char buffer[8192*16] = {0};
while (1) {
char buf[1024];
int n = read(fds[0], buf, 1024);
if (n <= 0) {
break;
}
memcpy(buffer, buf, n);
if (n != 1024) { break; }
}
printf("%s\n", buffer);
}
Volad Malevich
how to make a function with return output to buffer?
Volad Malevich
void output(char *buffer) ?
veficos
that's ok
Volad Malevich
return what?
veficos
void output(char *buffer)
{
int pid;
int fds[2];
pipe(fds);
pid = fork();
if(pid == 0){
close(1);
dup2(fds[1], 1);
close(fds[0]);
execlp("ps", "ps", "-a", NULL);
} else {
while (1) {
char buf[1024];
int n = read(fds[0], buf, 1024);
if (n <= 0) {
break;
}
memcpy(buffer, buf, n);
if (n != 1024) { break; }
}
}
}
...
char buffer[8192*16] = {0};
output(buffer);
Volad Malevich
void output(char *buffer)
{
int pid;
int fds[2];
pipe(fds);
pid = fork();
if(pid == 0){
close(1);
dup2(fds[1], 1);
close(fds[0]);
execlp("ps", "ps", "-a", NULL);
} else {
while (1) {
char buf[1024];
int n = read(fds[0], buf, 1024);
if (n <= 0) {
break;
}
memcpy(buffer, buf, n);
if (n != 1024) { break; }
}
}
}
...
char buffer[8192*16] = {0};
output(buffer);
thanks, but is ant way to put any command instead of "ps -A" as argument?
Volad Malevich
is execlp fits to do it?
Volad Malevich
for example "ps -A -o args | grep stop | grep 1765"

system() instead of execlp()
Volad Malevich
)) i need this one
Volad Malevich
var = output("system command");
Volad Malevich
i need this one, where output is a void output() function
veficos
void output(char* command, char *buffer)
{
int pid;
int fds[2];
pipe(fds);
pid = fork();
if(pid == 0){
close(1);
dup2(fds[1], 1);
close(fds[0]);
system(command);
} else {
while (1) {
char buf[1024];
int n = read(fds[0], buf, 1024);
if (n <= 0) {
break;
}
memcpy(buffer, buf, n);
if (n != 1024) { break; }
}
}
}
...
char buffer[8192*16] = {0};
output("ps aux", buffer);

I'd like to learn about one of these
Mr. COwO2 Preis
try emacs or vim
