                                  throws MemoryFault

Extracts environment data from the environ pointer

Parameters:

proc - Process whose environment is being extracted

environPointer - char ** environ value

Returns:

Environment properties

Throws:

MemoryFault

readEnvironmentStrings

public static Properties readEnvironmentStrings(IProcess proc,
                                                long environmentPtr)
                                         throws MemoryFault

Constructs a set of environment variable properties a the Windows environment variable string block. Documentation in MSDN: The GetEnvironmentStrings function returns a pointer to a block of memory that contains the environment variables of the calling process (both the system and the user environment variables). Each environment block contains the environment variables in the following format: Var1=Value1\0 Var2=Value2\0 Var3=Value3\0 .... VarN=ValueN\0\0

Parameters:

proc - - process whose environment variables are being extracted

environPtr - - address of Windows environment strings memory block

Returns:

Properties object containing list of process environment variable names and values

Throws:

MemoryFault
