Determines the user ID or group ID from a user or group name.

OSErr PBHMapNameSync (
    HParmBlkPtr paramBlock
);

Parameter descriptions

paramBlock

A pointer to an objParam variant of the HFS parameter block.

function result

A result code.

DISCUSSION

The relevant fields of the parameter block are:

• ioCompletion

  On input, a pointer to a completion function.

• ioResult

  On output, the result code of the function.

• ioNamePtr

  On input, a pointer to a pathname.

• ioVRefNum

  On input, a volume specification.

• ioObjType

  On input, the mapping function code; its value is 3 if you’re mapping a user name to a user ID or 4 if you’re mapping a group name to a group ID.

• ioObjNamePtr

  On input, a pointer to the user/ group name. The name is passed as a string. If NULL is passed, the ID returned is always 0. The maximum size of the name is 31 characters.

• ioObjID

  On output, the mapped user/group ID.

VERSION NOTES

Because user and group IDs are interchangeable under AFP 2.1 and later volumes, you might need to set the ioObjType field to determine which database (user or group) to search first. If both a user and a group have the same name, this field determines which kind of ID you receive.

AVAILABILITY

Supported in Carbon. Available in Carbon 1.0.2 and later when running Mac OS 8.1 or later.
