27.3.1 Determining the effective user name ¶

Function: mbfl_system_whoami ¶

Function: mbfl_system_whoami_var _RV ¶

Run the program whoami to determine the effective user name; print it on the standard output channel. If whoami is not executable or an error occurs executing it: return by calling return_failure().

We need to remember that a pathname to whoami is determined at package configuration time and hard–coded in the MBFL file; Gathering users data.
