fopen default authority

We have some code that is outputting data to the IFS and the security is
not behaving as expected.  The programmer is using the C runtime
functions and the code is similar to this:

 

// Open files...                                                  

pathnam = '/' + cojobd + '/';                                     

// Overpriced hard to implement payroll system import file...


filnam = pscomp + '_PU_' + %subst(cojobd:9:2) + '_' + creatdt + '.csv';


fullnam = %trim(pathnam) + %trim(filnam) ;                        

File_o = fopen(%trim(fullnam ):'w, codepage=850');                

rc = fclose(file_o);

 

I have created directories that have *PUBLIC *EXCLUDE and use an AUTL
list for the authorized users.  However, the file gets created with
*PUBLIC *RWX and no AUTL.  I'm assuming that the fopen runtime has a
default authority setup but can't seem to find that documented anywhere.
Does it have a default *PUBLIC authority and can I change it so that the
authority is pulled from the directory that the file is being created
in?
