NAME

       dlget() - retrieve information about a loaded module (program or shared library)

SYNOPSIS

       [flag]...  file...  [library]...

   Multithread Usage
       This routine is thread-safe.

DESCRIPTION

       is one of a family of routines that give the user direct access to the dynamic linking facilities.  returns information about a loaded mod-
       ule for a process.  retrieves information about a load module from an index specifying the placement of the  load  module  in  the  dynamic
       loader's  search list.  An index of requests information about the dynamic loader.  An index of requests information about the program file
       itself.

       If successful, returns a handle for the shared library as defined by the return value from

       desc must be preallocated by the user.  The structure members are filled in by the dynamic loader  with	information  about  the  requested
       shared library.

       A load_module_desc structure has the following members:

	      struct load_module_desc {
		 unsigned long text_base;
		 unsigned long text_size;
		 unsigned long data_base;
		 unsigned long data_size;
		 unsigned long unwind_base;
		 unsigned long linkage_ptr;
		 unsigned long phdr_base;
		 unsigned long tls_size;
		 unsigned long tls_start_addr;
		 }

       desc_size specifies the size in bytes of the load_module_desc structure sent in by the user.

       If a call to is unsuccessful, a NULL pointer is returned and desc remains unchanged.

ERRORS

       If fails, a subsequent call to returns one of the following values:
	      Cannot apply relocation in library.

	      Invalid descriptor argument.

	      Invalid descriptor version.

	      Invalid load module index.

	      Out of memory.
