_NAME_
getFilesStructCount

_PROTOTYPE_
int getFilesStructCount(char *dataFilePath, int structSize, int hasHeader);

_SHORT-DESCRIPTION_
Get the number of structs in a particular archive file

_DESCRIPTION_
getFilesStructCount is used to determine the number of data structs of
size structSize in the file pointed at by dataFilePath. It does this merely
by looking at the size of the file, subtracting out the number of bytes in
the standard CRIS/SIS data archive header if the flag hasHeader is
set (it usually will be), and then dividing by structSize. If the divide
does not return an integral number, getFilesStructCount will exit with
an error message.

_INPUT_
* dataFilePath is the string specifying the pathname of the data file
dataFilePath.
* structSize is the size of the structures the file should be made up of.
* hasHeader is a flag indicating whether the file should have a standard
CRIS/SIS data archive header in it in addition to the data. 

_OUTPUT_
* The number of data structures in the data file. Beware that
this is a "raw" number, which does not indicate whether there are
zeroed (no data in the struct) structures in the file or not.
