  • Method Details

    • getPcHeaderAddress

      public static Address getPcHeaderAddress(Program program)
      Returns the Address (if present) of the go pclntab section or symbol.
      Parameters:
      program - Program
      Returns:
      Address of go pclntab, or null if not present

    • hasPcHeader

      public static boolean hasPcHeader(Program program)
      Returns true if the specified program has an easily found pclntab w/pcHeader
      Parameters:
      program - Program
      Returns:
      boolean true if program has a pclntab, false otherwise

    • findPcHeaderAddress

      public static Address findPcHeaderAddress(GoRttiMapper programContext, AddressRange range, TaskMonitor monitor) throws IOException
      Searches (possibly slowly) for a pclntab/pcHeader structure in the specified memory range, which is typically necessary in stripped PE binaries.
      Parameters:
      programContext - GoRttiMapper
      range - memory range to search (typically .rdata or .noptrdata sections)
      monitor - TaskMonitor that will let the user cancel
      Returns:
      Address of the found pcHeader structure, or null if not found
      Throws:
      IOException - if error reading

    • isPcHeader

      public static boolean isPcHeader(ByteProvider provider) throws IOException
      Returns true if there is a pclntab at the current position of the specified ByteProvider.
      Parameters:
      provider - ByteProvider
      Returns:
      boolean true if the byte provider has the magic signature of a pclntab
      Throws:
      IOException - if error reading
