SANITIZE_INQUIRY_STR(9) 					  SCSI mid layer					   SANITIZE_INQUIRY_STR(9)

NAME
       sanitize_inquiry_string - remove non-graphical chars from an INQUIRY result string

SYNOPSIS
       void sanitize_inquiry_string(unsigned char * s, int len);

ARGUMENTS
       s
	   INQUIRY result string to sanitize

       len
	   length of the string

DESCRIPTION
       The SCSI spec says that INQUIRY vendor, product, and revision strings must consist entirely of graphic ASCII characters, padded on the
       right with spaces. Since not all devices obey this rule, we will replace non-graphic or non-ASCII characters with spaces. Exception: a NUL
       character is interpreted as a string terminator, so all the following characters are set to spaces.
