FSH_ISCURDIRPREFIX - Test for a prefix of a current directory
This function allows FSDs to disallow any modification of any directory
that is either a current directory of some process or the parent of any
current directory of some process. This is necessary because the kernel
manages the text of each current directory for each process.
int far pascal FSH_ISCURDIRPREFIX(pName)
char far * pMsg;
pName is a pointer to the path name.
The name must be in canonical form, that is, no '.' or ' ..' components,
uppercase, no meta characters, and full path name specified.
If no error is detected, a zero error code is returned. If an error is
detected, one of the following error codes is returned:
the specified path is a prefix of or is equal to the current directory of
If the current directory is the root and the path name is 'd:\ ',
ERROR_CURRENT_DIRECTORY will be returned.
FSH_ISCURDIRPREFIX takes the supplied path name, enumerates all current
directories in use, and tests to see if the specified path name is a
prefix or is equal to some current directory.
FSH_ISCURDIRPREFIX may block.
Note: OS/2 does not validate input parameters. An FSD, therefore, should
call FSH_PROBEBUF where appropriate.
