Name
-d44.5
Synopsis
The -d44.5 debugging switch displays the values
passed to sendmail’s internal
writable( ) routine. This routine nearly
duplicates the function of the access(3)
call[6] but does it much more safely and allows
checks to be made under the identity of the controlling user:
writable(fname, sff_flags)Here, the fname is the full pathname of the file
being checked. The sff_flags are documented in
Table 16-12 earlier. Success or failure is described
under -d44.4.
[6] It is more restrictive for root-owned files and can allow the set-user-id semantics needed for delivery to files.
