I actually went and downloaded bpl19 on the off chance that this had changed
since the version I have.  It hasn't; you are confused.  one_argument most
definitely expects to be able to write to the second buffer that you pass,
so it MUST be allocated memory, not a pointer set to NULL.  Change the
declarations to:

char name[MAX_INPUT_LENGTH], position[MAX_INPUT_LENGTH];

Just to be clear, str_cmp is not a standard C function.  It was specifically
written for convenience within the CircleMUD codebase.  DAK is also correct
that it is not necessary because one_argument() actually converts the
argument to lower case before copying it into the buffer you pass (the
original argument pointer is unmodified by the function itself).
