If you're copying a string, better to use strdup(). You won't make that off-by-one mistake that way.

UNKNOWN(1) General Commands Manual UNKNOWN(1)
NAME
unknown - identify possible genotypes for unknowns
SYNOPSIS
A program to rapidly identify which genotypes are possible for individuals typed as unknowns in the input pedigree.
unknown [ -cl ]
DESCRIPTION
unknown infers possible genotypes and mating combinations for parents with unknown genotypes for ilink(1), mlink(1) and linkmap(1).
OPTIONS
-c Use conditional allele frequencies.
-l Choose a good set of loop breakers automatically.
RETURN VALUE
0 Successful completion
ERRORS
10 File not found
255 Failure
EXAMPLES
Normally, unknown(1) is run immediately prior to its sister programs, ilink(1), mlink(1) and linkmap(1), like this:
unknown
mlink
FILES
unknown(1) reads the two files pedfile.dat and datafile.dat as its own input and produces various temporary files that are used as input to
the next program. These temporary files are ipedfile.dat, upedfile.dat, speedfile.dat and newspeedfile.dat.
NOTES
unknown(1) is part of the FASTLINK package, which is a re-implementation of the LINKAGE suite of computer tools that help investigate
genetic linkage as first proposed G.M. Lathrop, J.M. Lalouel, C. Julier, and J. Ott.
