Get the user name associated with the calling process
#include <unistd.h> int getlogin_r( char* name, size_t namesize );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The getlogin_r() function puts the login name of the user associated with the calling process in the character array pointed to by name. The array is namesize characters long and should have space for the name and the terminating NULL character. The maximum size of the login name is _POSIX_LOGIN_NAME_MAX.
If getlogin_r() is successful, name points to the name the user used at login, even if there are several login names with the same user ID.
