* Header to be able to compile the Zephyr kernel on top of a POSIX OS via the
|
|
* POSIX ARCH
|
|
*
|
|
* This file is only used in the POSIX ARCH, and not in any other architecture
|
|
*
|
|
* Most users will be normally unaware of this file existence, unless they have
|
|
* a link issue in which their POSIX functions calls are reported in errors (as
|
|
* zap_<origian_func_name>).
|
|
* If you do see a link error telling you that zap_something is undefined, it is
|
|
* likely that you forgot to select the corresponding Zephyr POSIX API.
|
|
*
|
|
* This header is included automatically when targeting POSIX ARCH boards
|
|
* (for ex. native_posix).
|
|
* It will be included in _all_ Zephyr and application source files
|
|
* (it is passed with the option "-include" to the compiler call)
|
|
*
|
|
* A few files (those which need to access the host OS APIs) will set
|
|
* NO_POSIX_CHEATS to avoid including this file. These are typically only
|
|
* the POSIX arch private files and some of the drivers meant only for the POSIX
|
|
* architecture.
|
|
* No file which is meant to run in an embedded target should set
|
|
* NO_POSIX_CHEATS

|
|
* native_posix.
|
|
*
|
|
* Without this header, both the Zephyr POSIX API functions and the equivalent
|
|
* host OS functions would have the same name. This would result in the linker
|
|
* not picking the correct ones.
|
|
*
|
|
* Renaming these functions allows the linker to distinguish
|
|
* which calls are meant for the Zephyr POSIX API (zap_something), and
|
|
* which are meant for the host OS.
|
|
*
|
|
* The zap_ prefix should be understood as an attempt to namespace them
|
|
* into something which is unlikely to collide with other real functions
|
|
* (Any unlikely string would have done)
|
|
*
|
|
* If you want to link an external library together with Zephyr code for the
|
|
* native_posix target, where that external library calls into the Zephyr
|
|
* POSIX API, you may want to include this header when compiling that library,
|
|
* or rename the calls to match the ones in the defines below.
