For capn_write_fd() the write() function would be ideal to pass as write_fd, but write() has type ssize_t (*)(int, const void *, size_t), whereas write_fd expects ssize_t (*)(int, void *, size_t). Passing write() directly with GCC 5.4 causes a warning -Wincompatible-pointer-types (on by default). |

capnpc-c
This is a C plugin for Cap'n Proto, an efficient protocol for sharing data and capabilities.
This is only the plugin, to properly make use of it you need to download, build and install capnpc and then build and install this project and then you can utilize it as:
capnpc compiler/test.capnp -oc
status
This is a merge of 3 forks of James McKaskill's great work, which has been untouched for a while:
usage
The compiler directory contains the C language plugin (capnpc-c) for use with the capnp tool: https://capnproto.org/capnp-tool.html.
capnp will by default search $PATH for capnpc-c - if it's on your PATH, you can generate code for your schema as follows:
$ capnp compile -o c myschema.capnp
Otherwise, you can specify the path to the c plugin:
$ capnp compile -o ./capnpc-c myschema.capnp
capnp generates a C struct that corresponds to each capn proto struct, along with read/write functions that convert to/from capn proto form.
TBD whether it will make sense in the future to provide accessor functions for struct members, rather than converting entire structs.
