elf_next3
Provide sequential access to the next archive member
Usage
#include <libelf.h>
Elf_Cmd
elf_next(Elf *elf);
Library
library “libelf”
Overview
The elf_next() function causes the ELF archive descriptor corresponding to argument elf to be adjusted to provide access to the next member in the archive on a subsequent call to elf_begin().
The return value of elf_next() is suitable for use in a loop invoking elf_begin().
Return values
If successful, function elf_next() returns the value ELF_C_READ. Otherwise, if argument elf was not associated with an archive, or if it was NULL, or if any other error occurred, the value ELF_C_NULL is returned.
Examples
To process all the members of an archive use:
Elf_Cmd cmd;
Elf *archive, *e;
...
cmd = ELF_C_READ;
archive = elf_begin(fd, cmd, NULL);
while ((e = elf_begin(fd, cmd, archive)) != (Elf *) 0)
{
... process `e' here ...
cmd = elf_next(e);
elf_end(e);
}
elf_end(archive);
Errors
Function elf_next() may fail with the following error:
- [ELF_E_ARGUMENT]
-
Argument elf was not associated with a containing ar(1) archive.
- [ELF_E_ARGUMENT]
-
An error was encountered while parsing the archive containing argument elf.
