Hello everyone,

How to use Linux API to get current user home directory, e.g. for user foo, the home directory is /home/foo, for user root, the home directory is /root.

thanks in advance,
George

I like to use

getenv("HOME");

Don't know if it's the best way to do it.

Standard way to do this:

Code:

#include <sys/types/h>
#include <pwd.h>
#include <inistd.h>

char *get_login_dir(char *dest)
{
     struct passwd *retval=getpwuid(getuid() );
      
     dest=NULL;
     if(retval!=NULL)
          strcpy(dest, retval->pw_dir);
     return dest;
}

In shell scripting you can just type $HOME
