system calls - valgrind give error when printing the second line to file -


i'm using valgrind find faults in code. command use 

 valgrind --leak-check=yes ./a.out

and compile code -g code alone. many errors pointing single write line (the 3 printed values initialized , defined). 

write (22,*) avlength, stdlength, avenergy

all conditional jump or move depends on uninitialised value(s) error. said line second line bunch of lines printing single file. @ end of errors, 2 more, 1 pointing line opening file

resstep = int(conf*100/iterate)                if (resstep.lt.10)                   write (resfile, "(a5,i1)") "res00",resstep                elseif (resstep.lt.100)                   write (resfile, "(a4,i2)") "res0",resstep                else                    write (resfile, "(a3,i1)") "res",resstep                endif                open (unit=22,file=trim(resfile),status='replace',       c                 action='write')

resstep integer. error syscall param write(buf) points uninitialised byte(s). finally, error address 0x52d83f4 212 bytes inside block of size 8,344 alloc'd when flush file (before closing it).

i can't find logic here. if problem opening file in faulty way, wouldn't error @ first line?

i use f95 compile , gcc version 4.1.2. can't upgrade of it.

wild guess: check data type of resfile. string or unit number?

my fortran 95 beyond rusty try moving call open() before calls write() , pass integer resunit instead of resfile first argument write():

character(len=20):: resfile integer(kind=2)  :: resunit, resstep  resstep = 1 resfile = 'my-results' resunit = 22 open (unit=resunit, file=trim(resfile), status='replace', action='write') write(resunit, "(a5,i1)") "res00", resstep  end

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
