Run process
suggest change#include <stdio.h>
void print_all(FILE *stream)
{
int c;
while ((c = getc(stream)) != EOF)
putchar(c);
}
int main(void)
{
FILE *stream;
/* call netstat command. netstat is available for Windows and Linux */
if ((stream = popen("netstat", "r")) == NULL)
return 1;
print_all(stream);
pclose(stream);
return 0;
}
This program runs a process (netstat
) via popen()
and reads all the standard output from the process and echoes that to standard output.
Note: popen()
does not exist in the standard C library, but it is rather a part of POSIX C)
Found a mistake? Have a question or improvement idea?
Let me know.
