SCANF
Synopsis
The F configuration
command (Section 22.1.2) allows the specification of a
scanf(3)-style string to aid in parsing files
(Section 22.1.2.1). This ability is enabled at compile
time by default. If you don’t need it, you can
exclude its support with the following line in your
Build m4 file:
APPENDDEF(`confENVDEF', `-DSCANF=0')
↑disable scanf(3)The scanf(3) function is used only in reading
files into a class with the F configuration
command.
If you are running a precompiled sendmail
binary, you can use the -d0.1 debugging
command-line switch (-d0.1) to determine if
SCANF support is included (if it appears in the list, support is
included).
