# 2) new value (scalar, scalar ref or list ref), or undef to delete tag
|

# 3-N) Options:
|
|
# Type => PrintConv, ValueConv or Raw - specifies value type
|

# AddValue => true to add to list of existing values instead of overwriting
|
|
# DelValue => true to delete this existing value value from a list, or
|
|
# or doing a conditional delete, or to shift a time value
|
|
# Group => family 0 or 1 group name (case insensitive)
|
|
# Replace => 0, 1 or 2 - overwrite previous new values (2=reset)
|
|
# Protected => bitmask to write tags with specified protections
|
|
# EditOnly => true to only edit existing tags (don't create new tag)
|
|
# EditGroup => true to only edit existing groups (don't create new group)
|
|
# Shift => undef, 0, +1 or -1 - shift value if possible
|
|
# NoFlat => treat flattened tags as 'unsafe'
|
|
# NoShortcut => true to prevent looking up shortcut tags
|
|
# ProtectSaved => protect existing new values with a save count greater than this
|
|
# CreateGroups => [internal use] createGroups hash ref from related tags
|
|
# ListOnly => [internal use] set only list or non-list tags
|
|
# SetTags => [internal use] hash ref to return tagInfo refs of set tags

# Returns: number of tags set (plus error string in list context)
|

# Notes: For tag lists (like Keywords), call repeatedly with the same tag name for

|
# otherwise just changed if it already exists. This may be
|
|
# overridden for file types with a PREFERRED metadata type.
|
|
# Set to 2 to create inidividual tags but not new groups
|
|
# EditOnly - flag set if tag should never be created (regardless of file type).
|
|
# If this is set, then IsCreating must be false
|
|
# CreateOnly - flag set if creating only (never edit existing tag)
|
|
# CreateGroups - hash of all family 0 group names where tag may be created
|
|
# WriteGroup - group name where information is being written (correct case)
|
|
# WantGroup - group name as specified in call to function (case insensitive)
|

# Next - pointer to next new value hash (if more than one)

|
# NoReplace - set if value was created with Replace=0

# AddBefore - number of list items added by a subsequent Replace=0 call
|
|
# IsNVH - Flag indicating this is a new value hash
|
|
# Shift - shift value
|
|
# Save - counter used by SaveNewValues()/RestoreNewValues()
