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 . |
