HA MACHINE SPECIFIC FUNCTIONS (machine.c/machine.h)

void md_init(void) 
	Set up machine specific signal handling etc. 

char *md_strcase(char *s)
	Set case of string to internal format and return pointer to string.  

char *md_arcname(char *name_req) 
	Construct archive name from requested name name_req and 
	return pointer to it.

void md_gethdr(int len) 
	Read len bytes of machine specific header information from arcfile.

void md_puthdr(void) 
	Write machine specific header information to arcfile. 

int md_filetype(char *path,char *name)
	Return file type (T_SKIP, T_DIR, T_REGULAR or T_SPECIAL) for 
	specified file and make it current file. This function is 
	responsible of skiping over archive file when packing. 

int md_newfile(void) 
	Setup machine specific header information for curren file 
	and return length of header.

int md_special(unsigned char **sdata)
	Point sdata to any data to be saved for special file (if any), 
	and return lenght of the data.

U32B md_curfilesize(void) 
	Return file size for current file.

U32B md_curfiletime(void) 
	Returns file time for current file

int md_mkspecial(char *ofname,unsigned sdlen,unsigned char *sdata)
	Make special file ofname using current machine specific header 
	and sdlen bytes of information in sdata. 
	Return zero on failure nozero on success.

void md_setft(char *file,U32B time) 
	Set filetime for file to time.

void md_setfattrs(char *file) 
	Set attributes (from machine specific heador) of file 
	if useattr is nonzero. 

U32B md_systime() 
	get system time.

void md_listhdr(void) 
	print feader for file attributes to stdout.

void md_listdat(void) 
	print attribute information from machine specific header.

char *md_timestring(unsigned long t) 
	Return pointer to string representin "unix time" t.

void md_truncfile(int fh, U32B len) 
	Truncate file pointed by handle fh to length len.

char *md_tohapath(char *mdpath) 
	Construct internal representation for path mdpath.

char *md_tomdpath(char *hapath) 
	Construct machine representation for path hapath. 

char *md_strippath(char *mdfullpath) 
	Return path part of mdfullpath.

char *md_stripname(char *mdfullpath) 
	Return name part of mdfullpath. 

char *md_pconcat(int delim, char *head, char *tail) 
	Construct path from head, tail. This function is supposed to malloc
	space for path. other parts of HA call free with returned pointer !

int md_namecmp(char *pat, char *cmp) 
	Return nonzero if pattern pat matches filename cmp using
	wildcards in machine specific manner.
