sion_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
Name of file to be opened Object file version stamp Symbol table version stamp Address of file in memory Identifier of tool version entry
Numeric tool version from toolname's entry 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.
