NAME
AddFreeList - add memory to the free list
SYNOPSIS
status = AddFreeList( free, mem, len )
D0 A0 A1 A2
FUNCTION
This routine adds the specified memory to the free list.
The free list will be extended (if required). If there
is not enough memory to complete the call, a null is returned.
Note that AddFreeList does NOT allocate the requested memory.
It only records the memory in the free list.
INPUTS
free -- a pointer to a FreeList structure
mem -- the base of the memory to be recorded
len -- the length of the memory to be recorded
RESULTS
status -- nonzero if the call succeeded.

NAME
BumpRevision - reformat a name for a second copy
SYNOPSIS
result = BumpRevision( newbuf, oldname )
D0 A0 A1
FUNCTION
BumpRevision takes a name an turns it into a "copy of name".
It knows how to deal with copies of copies. The routine
will truncate the new name to the maximum dos name size
(currently 30 characters).
INPUTS
newbuf - the new buffer that will receive the name (it must
be at least 31 characters long).
oldname - the original name
RESULTS
result - a pointer to newbuf
EXCEPTIONS
EXAMPLE
oldname newbuf
------- ------
"foo" "copy of foo"
"copy of foo" "copy 2 of foo"
"copy 2 of foo" "copy 3 of foo"
"copy 199 of foo" "copy 200 of foo"
"copy foo" "copy of copy foo"
"copy 0 of foo" "copy 1 of foo"
"012345678901234567890123456789" "copy of 0123456789012345678901"

NAME
FindToolType - find the value of a ToolType variable
SYNOPSIS
value = FindToolType( toolTypeArray, typeName )
D0 A0 A1
FUNCTION
This function searches a tool type array for a given entry,
and returns a pointer to that entry. This is useful for
finding standard tool type variables. The returned
value is not a new copy of the string but is only
a pointer to the part of the string after typeName.
INPUTS
toolTypeArray - an array of strings
typeName - the name of the tooltype entry
RESULTS
value - a pointer to a string that is the value bound to
typeName, or NULL if typeName is not in
the toolTypeArray.
EXCEPTIONS
EXAMPLE
Assume the tool type array has two strings in it:
"FILETYPE=text"
"TEMPDIR=:t"
FindToolType( toolTypeArray, "FILETYPE" ) returns "text"
FindToolType( toolTypeArray, "TEMPDIR" ) returns ":t"
FindToolType( toolTypeArray, "MAXSIZE" ) returns NULL

NAME
FreeDiskObject - free all memory in a Workbench disk object
SYNOPSIS
FreeDiskObject( diskobj )
A0
FUNCTION
This routine frees all memory in a Workbench disk object, and the
object itself. It is implemented via FreeFreeList().
GetDiskObject() takes care of all the initialization required
to set up the objects free list. This procedure may ONLY
be called on DiskObject allocated via GetDiskObject().
INPUTS
diskobj -- a pointer to a DiskObject structure
RESULTS

NAME
FreeFreeList - free all memory in a free list
SYNOPSIS
FreeFreeList( free )
A0
FUNCTION
This routine frees all memory in a free list, and the
free list itself. It is useful for easily getting
rid of all memory in a series of structures. There is
a free list in a Workbench object, and this contains
all the memory associated with that object.
A FreeList is a list of MemList structures. See the
MemList and MemEntry documentation for more information.
If the FreeList itself is in the free list, it must be
in the first MemList in the FreeList.
INPUTS
free -- a pointer to a FreeList structure
RESULTS

icon.library/GetDiskObject icon.library/GetDiskObject
NAME
GetDiskObject - read in a Workbench disk object
SYNOPSIS
diskobj = GetDiskObject( name )
D0 A0
FUNCTION
This routine reads in a Workbench disk object in from disk. The
name parameter will have a ".info" postpended to it, and the
info file of that name will be read. If the call fails,
it will return zero. The reason for the failure may be obtained
via IoErr().
Using this routine protects you from any future changes to
the way icons are stored within the system.
A FreeList structure is allocated just after the DiskObject
structure; FreeDiskObject makes use of this to get rid of the
memory that was allocated.
INPUTS
name -- name of the object
RESULTS
diskobj -- the Workbench disk object in question

icon.library/MatchToolValue icon.library/MatchToolValue
NAME
MatchToolValue - check a tool type variable for a particular value
SYNOPSIS
result = MatchToolValue( typeString, value )
D0 A0 A1
FUNCTION
MatchToolValue is useful for parsing a tool type value for
a known value. It knows how to parse the syntax for a tool
type value (in particular, it knows that '|' separates
alternate values).
INPUTS
typeString - a ToolType value (as returned by FindToolType)
value - you are interested if value appears in typeString
RESULTS
result - a one if the value was in typeString
EXCEPTIONS
EXAMPLE
Assume there are two type strings:
type1 = "text"
type2 = "a|b|c"
MatchToolValue( type1, "text" ) returns 1
MatchToolValue( type1, "data" ) returns 0
MatchToolValue( type2, "a" ) returns 1
MatchToolValue( type2, "b" ) returns 1
MatchToolValue( type2, "d" ) returns 0
MatchToolValue( type2, "a|b" ) returns 0

icon.library/PutDiskObject icon.library/PutDiskObject
NAME
PutDiskObject - write out a DiskObject to disk
SYNOPSIS
status = PutDiskObject( name, diskobj )
D0 A0 A1
FUNCTION
This routine writes out a DiskObject structure, and its
associated information. The file name of the info
file will be the name parameter with a
".info" postpended to it. If the call fails, a zero will
be returned. The reason for the failure may be obtained
via IoErr().
Using this routine protects you from any future changes to
the way icons are stored within the system.
INPUTS
name -- name of the object
diskobj -- a pointer to a DiskObject
RESULTS
status -- non-zero if the call succeeded
