/* sane - Scanner Access Now Easy.
对 sane标准头文件的扩展
Author : Gongbing
Date : 2022 - 01 - 14
Path : SANE_CONFIG_DIR
This environment variable specifies the list of directories that may contain theconfiguration file . Under UNIX ,
the directories are separated by a colon ( : ' ) , under os / 2 , they are separated by a semi - colon ( ; ' ) . If this variable
is not set , the configuration file is searched in two default directories : first , the currentworking directory ( " . " )
and then in letc / sane . d . If the value of the environmentvariable ends with the directory separator character ， then
the default directoriesare searched after the explicitly specified directories . For example ， setting SANE_CONFIG_DIR
to " /tmp/config : " would result in directories tmp / config , . , andletclsane . d being searched ( in this order ) .
