NAME
       elf_errno - retrieve the error code of the last failing libelf function
       call.


SYNOPSIS
       #include <libelf.h>

       int elf_errno(void);


DESCRIPTION
       The elf_errno function retrieves the error code of the last failing
       libelf library function. This error code indicates the type of error
       that occurred during the failing function call.  Each thread maintains
       its own separate error code.


PARAMETERS
       This function does not take any parameters.


RETURN VALUE
       The elf_errno function returns an integer representing the most recent
       error code for the current thread. If no error has occurred, it returns
       0. If an error occurred, the function returns a non-zero error code
       that corresponds to the specific error.  Error codes can be passed to
       elf_errmsg in order to create a string describing the error.
