NAME

       coap - Overview of the libcoap library

SYNOPSIS

       Summary of the different libcoap API manual pages.

DESCRIPTION

       libcoap is a C implementation of a lightweight application-protocol for devices that are
       constrained by their resources such as computing power, RF range, memory, bandwidth, or
       network packet sizes. This protocol, CoAP, is standardized by the IETF as RFC7252. For
       further information related to CoAP, see http://coap.technology.

       Documentation for the specific library calls with examples can be found in the man pages
       referred to in SEE ALSO.

       Further information can be found in the include header files with example code provided in
       the examples directory.

       NOTE: This documentation is a work in progress. Any missing information can be found in
       the include header files along with example code provided in the examples directory.
