An elegant way to generate HTTP/1.x messages in C

creq is a library written in pure C, which allows you to create HTTP/1.x message strings at your own wishes with easy-to-use object-like APIs. With high performance and adjustable memory usage, creq can be used in low-profile MCUs, such as Arduino(AVR) and ESP-series.

• Customizable request/response generation
• Safe & tweakable memory management
• Great portability
• User-friendly object-like interface
• Integrated message syntax validator

When compiling for windows, we specify a specific calling convention to avoid issues where we are being called from a project with a different default calling convention. For windows you have 3 define options:

• CREQ_HIDE_SYMBOLS - Define this in the case where you don't want to ever dllexport symbols
• CREQ_EXPORT_SYMBOLS - Define this on library build when you want to dllexport symbols (default)
• CREQ_IMPORT_SYMBOLS - Define this if you want to dllimport symbol

For Unix builds that support visibility attribute, you can define similar behavior by setting default visibility to hidden by adding

• -fvisibility=hidden (for gcc)
• -xldscope=hidden (for sun cc)

to CFLAGS, then using the CREQ_API_VISIBILITY flag to "export" the same symbols the way CREQ_EXPORT_SYMBOLS does
