I have two calls to two different methods :
void func1()
{
// do something
if (fail)
{
// then set errno to EEXIST
}
}
And the second method :
void func2()
{
// do something
if (fail)
{
// then set errno to ENOENT
}
}
When I set the
errno
to some value , what does it do ? just error checking ?How can I set
errno
in the above methodsfunc1
andfunc2
toEEXIST
andENOENT
Thanks
