NAME

ada.rmlib − remove an Ada library

SYNOPSIS

ada.rmlib [ -f ] libraryname

DESCRIPTION

Ada.rmlib removes the Ada library (directory) libraryname. 

If the standard input is a terminal, ada.rmlib requests confirmation before removing an Ada library.  Confirmation is not requested if the −f option is given or if the standard input is not a terminal. 

Removal of an Ada library requires write permission in its parent directory and recursively in all its subdirectories, but neither read nor write permission on the files within it. 

The following options are recognized:

−f Do not ask for confirmation before removing the Ada library. 

Environment Variables

Two environment variables, ADA_PATH and ADA_PREDEF_LIB, are associated with all components of the the Ada compilation system.  Both must be set properly and exported before any component of the Ada compilation system (including ada.rmlib) can be used (see ada(1), Environment Variables). 

Locks

To ensure the integrity of their internal data structures, Ada libraries and families are locked for the duration of operations that are performed on them.  Normally Ada families are locked only briefly when a library is added, removed, or renamed; however, sometimes multiple Ada libraries must be locked for longer periods during a single operation.  If more than one library is locked, ada places an exclusive lock on one library, for updating, and a shared lock on any others to remain open for read-only purposes. 

An Ada family or library locked for updating cannot be accessed in any way by any part of the Ada compilation system except by the locking agent.  An Ada family or library locked for reading can be accessed by any part of the Ada compilation system for read-only purposes. 

If ada.rmlib cannot obtain a lock, it displays an informational message and terminates. 

Under some circumstances, an Ada family or Ada library might be locked, but the locking program(s) might have terminated (for example, due to system crash or network failure).  If you determine that the Ada family or Ada library is not actually locked, you may remove the lock. 

Use ada.unlock(1) to unlock an Ada library and the UNLOCK command of ada.fmgr(1) to unlock an Ada family.  However, unlocking should be done with care.  If an Ada family or Ada library is actually locked by a tool, unlocking it permits access by other tools that might find the contents invalid or might damage the Ada family or Ada library. 

DIAGNOSTICS

Ada.rmlib returns exit status 0 if the Ada library was successfully removed; otherwise, a diagnostic is issued and a non-zero exit status is returned. 

WARNINGS

An Ada library is a directory containing files used by the Ada compilation system.  Users are strongly discouraged from placing any user files or directories in Ada library directories.  User files/directories in Ada libraries are subject to damage by or might interfere with proper operation of the Ada compilation system.  In particular, ada.rmlib attempts to remove all such files and subdirectories. 

Lack of write permission to the parent directory or subdirectories causes ada.rmlib to fail to correctly remove the Ada library and leads to partial destruction of the structure under the Ada library. 

Removing an Ada library when your current working directory is the Ada library directory or a subdirectory of the Ada library directory might lead to an incompletely removed Ada library.
