HEADER_ID
HEADER_ID = 0x7875 : int
Info-ZIP New Unix Extra Field: ====================================.
Currently stores Unix UIDs/GIDs up to 32 bits. (Last Revision 20080509)
Value Size Description
(UnixN) 0x7875 Short tag for this extra block type ("ux") TSize Short total data size for this block Version 1 byte version of this extra field, currently 1 UIDSize 1 byte Size of UID field UID Variable UID for this entry GIDSize 1 byte Size of GID field GID Variable GID for this entry
Currently Version is set to the number 1. If there is a need to change this field, the version will be incremented. Changes may not be backward compatible so this extra field should not be used if the version is not recognized.
UIDSize is the size of the UID field in bytes. This size should match the size of the UID field on the target OS.
UID is the UID for this entry in standard little endian format.
GIDSize is the size of the GID field in bytes. This size should match the size of the GID field on the target OS.
GID is the GID for this entry in standard little endian format.
If both the old 16-bit Unix extra field (tag 0x7855, Info-ZIP Unix) and this extra field are present, the values in this extra field supercede the values in that extra field.
