SYNOPSIS

windmc [options] elf_file

PARAMETERS

-h
    Display help information. Prints command usage.

-v
    Enable verbose mode. Prints verbose information.

-patch

DESCRIPTION

The windmc command is a utility provided by Wind River Systems, primarily used for manipulating ELF (Executable and Linkable Format) files. These files are common in embedded systems development, especially those utilizing Wind River's VxWorks real-time operating system. windmc allows for various operations on ELF files, including extracting symbol information, modifying sections, and potentially other tasks related to debugging, analysis, and optimization. Its precise functionality can vary based on the specific version and build tools installed. The command acts like a swiss army knife for developers working on VxWorks images and other ELF based targets. It allows examining and modifying the ELF image. The modifications can range from patching some bytes to adding custom sections to the ELF file. The command needs to be used with caution as it can lead to corrupted ELF files.

CAVEATS

Improper usage of windmc can corrupt ELF files, rendering them unusable. Backups are highly recommended before making any modifications.
The specific options and capabilities of windmc depend on the Wind River development environment installed.

USAGE NOTES

windmc is usually part of a larger Wind River development environment and is not a standard Linux utility. Ensure that you have the correct environment variables and tools configured to use it.
When patching, the should be in hexadecimal, and the will depend on the targeted instruction set and data type.
