USAGE: ffindex_build [-a|-v] [-s] [-f file]* OUT_DATA_FILE OUT_INDEX_FILE [-d 2ND_DATA_FILE -i 2ND_INDEX_FILE] [DIR_TO_INDEX|FILE]*

-a

append files/indexes, also needed for sorting an already existing ffindex

-d FFDATA_FILE

-f FILE

file containing a list of file names, one per line -f can be specified up to 4096 times

-s

sort index file, so that the index can queried. Another append operations can be done without sorting.

-v

ENVIRONMENT

• FFINDEX_MAX_INDEX_ENTRIES - allocate memory for this number of entries

EXAMPLES:

• Create a new ffindex containing all files from the "bar/" directory containing say myfile1.txt, myfile2.txt and sort (-s) it so that e.g. ffindex_get can use it.

• $ ffindex_build -s foo.ffdata foo.ffindex bar/

• Add (-a) more files: myfile3.txt, myfile4.txt.

• $ ffindex_build -a foo.ffdata foo.ffindex myfile3.txt myfile4.txt

• Oops, forgot to sort it (-s) so do it afterwards:

• $ ffindex_build -as foo.ffdata foo.ffindex

NOTE:

• Maximum key/filename length is 63 and maximum entries are by default 80000000 This can be changed in the sources.
