TCLAP is a small, flexible library that provides a simple interface for defining and accessing command line arguments. I try to design the command parser but have seen totally different approaches on internet. identify the header is real or The final result code marks the end of an AT command and can be OK, ERROR or ABORTED: when the final result is an error, be sure to handle it before continuing with the next AT command; The information text response format is command specific. Modems usually use serial communication and inside the embedded world it AT command server written in C++. 2. Parse is called, it is only considering the options defined by GlobalOptions. What we usually want is something like: The getopt() function is a builtin function in C and is used to parse command line arguments. Forum. g. And if you'd like to process command line parameters in a way similar to most UNIX commands, the function you're probably looking for is getopt() Good luck! You should pass a buffer as a parameter and use it in the read, so the calling function can see the result of the last command, but I'd keep the integer return code because doing strcmp(buf,"OK") at every command would again be duplicating code. Among them, Jarro2783’s cxxopts stands out, particularly for simpler programs, I'm currently using it on a project related to my Portable recognised a command my parser goes into the waiting for parameters state where I actually begin looking for the end delimiter.
