How can I link to a specific glibc version?
...ric
so in menuconfig I do:
Operating System
Version of linux
so I select:
4.14.71
which is the first equal or older version. It has to be older since the kernel is backwards compatible.
Now you can build with:
env -u LD_LIBRARY_PATH time ./ct-ng build CT_JOBS=`nproc`
and now wait for...
What is the string length of a GUID?
I want to create a varchar column in SQL that should contain N'guid' while guid is a generated GUID by .NET ( Guid.NewGuid ) - class System.Guid.

...ing puts.c source code
#include <stdio.h>
int main(int argc, const char *argv[])
{
while (*++argv) puts(*argv);
return 0;

It will not compile because argc is unused, and the settings are hardcore (-W -Wall -pedantic -Werror).
There are 5 things you could do:

else
puts("stdin is NOT connected to a terminal");

Difference between malloc and calloc?
...ngful. Also note that calloc doesn't necessarily do what you think for non-char types. Nobody really uses trap representations any more, or non-IEEE floats, but that's no excuse for thinking your code is truly portable when it isn't.

Assign one struct to another in C
...ment is supported for structs. However, there are problems:
struct S {
char * p;
};
struct S s1, s2;
s1.p = malloc(100);
s2 = s1;
Now the pointers of both structs point to the same block of memory - the compiler does not copy the pointed to data. It is now difficult to know which struct insta...
