The output file, if not specified on the command line, is named source_file.dat.
The options are as follows:
STR_ORDERED
bit in the header
str_flags
field to be set.
STR_RANDOM
bit in the header
str_flags
field to be set.
STR_ROTATED
bit in the header
str_flags
field to be set.
The format of the header is:
#define VERSION 1
unsigned long str_version; /* version number */
unsigned long str_numstr; /* # of strings in the file */
unsigned long str_longlen; /* length of longest string */
unsigned long str_shortlen; /* length of shortest string */
#define STR_RANDOM 0x1 /* randomized pointers */
#define STR_ORDERED 0x2 /* ordered pointers */
#define STR_ROTATED 0x4 /* rot-13'd text */
unsigned long str_flags; /* bit field for flags */
char str_delim; /* delimiting character */
All fields are written in big-endian byte order.
The purpose of unstr is to undo the work of strfile. It prints out the strings contained in the file source_file in the order that they are listed in the header file source_file.dat to standard output. It is possible to create sorted versions of input files by using -o when strfile is run and then using unstr to dump them out in the table order.
