Schorr <aschorr@telemetry-investments.com> + Make sure that all field values, and therefore all strings inside gawk, + are terminated with a '\0' character! + * field.c (databuf): New static struct to hold info about our buffer to + contain the field string values. + (allocate_databuf): New function to make sure the databuf is large + enough to hold $0 and copies of $1 through $NF. + (set_field): Copy $n into free space previously allocated in databuf + and add a '\0' at the end. + (rebuild_record): Call allocate_databuf to ensure sufficient space + for copying non-malloced field values. When copying field values, + use databuf to create a NUL-terminated copy. + (purge_record): New function extracted from reset_record to initialize + $1 through $NF to null values. + (set_record): Buffer management moved to new allocate_databuf function. + Call purge_record instead of reset_record, since reset_record contains + some extra logic not needed in this case. + (reset_record): Call purge_record to do most of the work, and call + allocate_databuf to make sure we have a big enough buffer to contain + copies of the $1 through $NF. + +2016-07-06 Andrew J.
