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.
