NAME
       elf_cntl - control a file descriptor

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

DESCRIPTION
       instructs  the  library	to  modify its behavior with respect to an ELF descriptor, elf.  As elf_begin(3E) describes, an ELF descriptor can
       have multiple activations, and multiple ELF descriptors may share a single file descriptor.  Generally, commands apply to  all  activations
       of  elf.   Moreover,  if  the  ELF  descriptor  is associated with an archive file, descriptors for members within the archive will also be
       affected as described below.  Unless stated otherwise, operations on archive members do not affect the descriptor for  the  containing  ar-
       chive.

       The cmd argument tells what actions to take and may have the following values.

       This value tells the library not to use the file
			 descriptor  associated with elf.  A program should use this command when it has requested all the information it cares to
			 use and wishes to avoid the overhead of reading the rest of the file.	The memory for all  completed  operations  remains
			 valid, but later file operations, such as the initial for a section, will fail if the data is not in memory already.

       This command is similar to
			 except it forces the library to read the rest of the file.  A program should use this command when it must close the file
			 descriptor but has not yet read everything it needs from the file.  After completes the command, future operations,  such
			 as will use the memory version of the file without needing to use the file descriptor.

       If succeeds, it returns zero.  Otherwise, elf was null or an error occurred, and the function returns -1.

   Note
       If  the	program  wishes  to  use  the  ``raw'' operations (see described in elf_getdata(3E), and elf_rawfile(3E)) after disabling the file
       descriptor with or it must execute the raw operations explicitly beforehand.  Otherwise, the raw file operations will fail.  Calling  makes
       the entire image available, thus supporting subsequent calls.
