5.1.1 Switch variables

These variables represent a flag which can be turned on or off. If their value is on or 1 they are turned on, if their value is off or 0 they are turned off. All other values are ignored. If the same flag can be turned on or off using config files, the environmental variable always has the priority.

LD_ZLIB_VERBOSE
If this variable is turned on, informational messages are printed on many operations of zlibc. Moreover, error messages are printed in order to point out errors in the configuration files, if any. If this variable is turned off, errors are silently ignored.

LD_ZLIB_UNLINK
If this variable is turned on, and if the user program tries to unlink a virtual (uncompressed) file, zlibc translates this call into unlinking the real file. If this variable is turned off, unlink calls on virtual files are ignored.

LD_ZLIB_DISABLE
If this variable is turned on, zlibc is switched off.

LD_ZLIB_READDIR_COMPR
If this variable is turned on, the readdir function shows the real (compressed) files instead of the virtual (uncompressed) files.
