Parsing command-line options is a tedious chore. Luckily, the GNU C library provides a function that you can use in C and C++ programs to make this job somewhat easier (although still a bit annoying).This function,getopt_long, understands both short and long options. If you use this funct...
Argtable3is an open source ANSI C library that parses GNU-style command-line options with thegetoptlibrary. It simplifies command-line parsing by defining a declarative-style API that you can use to specify what your command-line syntax looks like. Argtable3 will automatically generate consistent...
Similarly to the previous, due to related changes in string parsing, adjacent string literals (either wide or narrow character string literals) without any whitespace were interpreted as a single concatenated string in previous releases of Visaul C++. In Visual Studio 2015, you must now add whitesp...
This is the popt(3) command line option parsing library. While it is similar to getopt(3), it contains a number of enhancements, including: 1) popt is fully reentrant 2) popt can parse arbitrary argv[] style arrays while getopt(3) makes this quite difficult 3) popt allows users to ali...
