Some minor refactoring in inivar, most is related to Clang-Tidy and Clang warnings. - Renamed a couple of variables. - Be more consistent regarding return value, -1 on error and 1 if variable is not found, 0 is still success. - Change to headers adapted for C++. - Simplified conditions for several of the if-statements. - Removed two unused headers. - Use strtol() instead of sscanf() to get number from command-line argument. This also sets a limit of accepted numbers between 0 and 'INT_MAX'. - Change name for '-num' argument to 'occurrence_number'.
Include information that the return value can be NULL.
This includes information about all command-line arguments. The section 'SEE ALSO' has been removed.
