NAME

lfanew - manipulate fat binary programs wrapped in MZ files

SYNOPSIS

lfanew [ -k ] -o < out-stub-file > < in-stub-file >
lfanew -S [ -k ] [ -p ] -o < out-fat-file > < in-payload-file > < in-stub-file >
lfanew -U [ -k ] -o < out-payload-file > < in-fat-file >

DESCRIPTION

By default, lfanew adds a .e_lfanew header field to an old-style MZ executable, so that the program can be used as an MS-DOS loader stub for a NE/PE executable.

With -S ("stubify"), lfanew creates a "fat" binary by combining an MZ stub with a NE/PE payload.

With -U ("unstubify"), lfanew extracts a NE/PE payload from a "fat" binary, removing any MZ stub.

OPTIONS

-k

Keeps the output if an error is encountered, instead of deleting it.

-p

Derives the stub size from .e_cp and .e_cblp , rather than from .e_lfanew .

NOTES

lfanew can add a stub to a Portable Executable payload if there is enough RVA space before the PE sections to accommodate the stub and PE headers. PE executables generally need to be unstubified before a different stub can be attached.
