    ystem commands for consoles

    ok, i know system("pause") when you #include <stdlib.h>. but what is the command for makeing the system wait for say... 2 seconds?

    i think its system("sleep") but i dont know how to set the time for it.

    but this is what i need, i need it to look like its processing something when really its doing nothing and quickly executes a block of code like 2 seconds later.

    there is no source code or anything to display, i need the system command, is all.

    Why not write your own delay function like me?

    Code:
    void delays(unsigned msecs)
    {
        long ticks;
    
        ticks = biostime(0,0);
        while ((biostime(0,0)-ticks)/CLK_TCK*1000 < msecs)
        {
        }
    }
    or just use the delay (not sure in witch header file)

    And windows machines have:
    Sleep(millisec);

    On unix you may have sleep() in unistd.h

    Here's some more portable code:
    Code:
    #include <time.h>
    
    void sleep_seconds ( long seconds ) {
      clock_t limit, now = clock();
      limit = now + seconds * CLOCKS_PER_SEC;
      while ( limit > now )
        now = clock();
    }
    void sleep_ticks ( long ticks ) {
      clock_t limit, now = clock();
      limit = now + ticks;
      while ( limit > now )
        now = clock();
    }
    But remember, high speed looping often causes high CPU usage, which is a good reason for finding your compiler/OS's sleep function.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
