.Sh NAME
|
||||
.Nm elf_getversion
|
||||
.Nd retrieve the operating version for an ELF object
|
||||
.Sh LIBRARY
|
||||
.Lb libelf
|
||||
.Sh SYNOPSIS
|
||||
.In libelf.h
|
||||
.Ft unsigned int
|
||||
.Fn elf_getversion "Elf *elf"
|
||||
.Sh DESCRIPTION
|
||||
.Em Important :
|
||||
The function
|
||||
.Fn elf_getversion
|
||||
is an extension to the
|
||||
.Xr ELF 3
|
||||
API.
|
||||
Applications that need to be portable to other implementations of
|
||||
.Li libelf
|
||||
should take care not to use this function.
|
||||
.Pp
|
||||
The function
|
||||
.Fn elf_getversion
|
||||
returns the operating version for the ELF descriptor pointed to by
|
||||
argument
|
||||
.Fa elf .
|
||||
.Pp
|
||||
This descriptor must have been allocated by a previous call to one of
|
||||
the functions that return an ELF descriptor, such as
|
||||
.Xr elf_begin 3 ,
|
||||
.Xr elf_memory 3 ,
|
||||
.Xr elf_open 3
|
||||
and
|
||||
.Xr elf_openmemory 3 .
|
||||
The object associated with the descriptor
|
||||
.Fa elf
|
||||
should be an ELF object.
|
||||
.Sh RETURN VALUES
|
||||
The function returns the operating version for the ELF object if
|
||||
successful or
|
||||
.Dv EV_NONE
|
||||
if an error occurred.
|
||||
.Sh COMPATIBILITY
|
||||
This function is an extension to the
|
||||
.Xr ELF 3
|
||||
API set.
|
||||
.Sh ERRORS
|
||||
This function can fail with the following errors:
|
||||
.Bl -tag -width "[ELF_E_ARGUMENT]"
|
||||
.It Bq Er ELF_E_ARGUMENT
|
||||
The argument
|
||||
.Fa elf
|
||||
was
|
||||
.Dv NULL .
|
||||
.It Bq Er ELF_E_ARGUMENT
|
||||
The underlying object referenced by the descriptor
|
||||
.Fa elf
|
||||
was not an ELF object.
|
||||
.El
|
||||
.Sh SEE ALSO
|
||||
.Xr elf 3 ,
|
||||
.Xr elf_begin 3 ,
|
||||
