* Determines if the file passed in is a patch or not.

* This function will take a pointer to a string filename, open it,

* print its findings out to the console if the pStruct verbose flag
* is set.
*
* If the file passed in doesn't exist, it is created and returned as
* a pointer to the writable FILE for use with fwrite and other
* writing stream functions. (For creating patches, or target files)
*
* @param char* argument: The filename passed into the function.
* @param pStruct: The parameter structure to set the function
* pointers this function deems will open the file, and with a verbose
* flag set prints out information to the console about its
* findings.
*
* @return int: Returns the FILE pointer if the passed in argument is
* a path to a valid patch file, (Or to a new file where a patch will
* be written) and NULL otherwise.
