NAME
  st_get_known_versions, st_get_format_versions, st_mem_get_format_versions,
  st_get_version_byname, st_mem_get_version_byname, st_fd_get_version_byname
  - Access version information in an object file

LIBRARY
  Symbol Table and Object File Access Library (libst.a)

SYNOPSIS
  #include <st.h>

  st_status_t st_get_known_versions (
	  unsigned short *objver,
	  unsigned short *symver);

  st_status_t st_get_format_versions (
	  char *objname,
	  unsigned short *objver,
	  unsigned short *symver);

  st_status_t st_mem_get_format_versions (
	  void *addr,
	  unsigned short *objver,
	  unsigned short *symver);

  st_status_t st_get_version_byname (
	  char *objname,
	  char *toolname,
	  unsigned long *toolver,
	  char **verstring);

  st_status_t st_mem_get_version_byname (
	  void *addr,
	  unsigned long size,
	  char *toolname,
	  unsigned long *toolver,
	  char **verstring);

  st_status_t st_fd_get_version_byname (
	  int fd,
	  off_t pos,
	  char *toolname,
	  unsigned long *toolver,
	  char **verstring);

PARAMETERS
  objname or filename
    Name of file to be opened

  objver
    Object file version stamp

  symver
    Symbol table version stamp

  addr
    Address of file in memory

  toolname
    Identifier of tool version entry

  toolver
    Numeric tool version from toolname's entry

  verstring
    Printable tool version from toolname's entry

DESCRIPTION
  These functions access version information in an object file.	 The
  st_get_known_versions routine returns the version stamp values (from the
  file /usr/include/stamp.h) that libst.a was built with.  The
  st_get_format_versions and st_mem_get_format_versions retrieve the object
  file and symbol table version stamps from a given object file.  Use
  st_mem_get_format_versions if the contents of the object have been memory-
  mapped or read into memory and st_get_format_versions otherwise.

  The st_get_version_byname, st_mem_get_version_byname, and
  st_fd_get_version_byname routines search the .comment section for a tool-
  specific version entry for the tool identified by the toolname parameter.
  Tool-specific versions are typically recorded only for system utilities.
  Use st_fd_get_version_byname for a file that has already been opened,
  st_mem_get_version_byname for a file that has been read into memory, and
  st_get_version_byname otherwise.  The caller is responsible for freeing the
  verstring parameter after a successful call; space for this character
  string is dynamically allocated by these libst functions.

RETURN VALUES
  All routines return zero to indicate success and non-zero to indicate
  failure.
