Detailed Description

A parser for command line arguments.

A general purpose command line parser that uses getopt_long() to parse the command line.

Definition in file cmdLineParser.c.

Macro Definition Documentation

#define nextOption ( o ) ((MyOption*) o->next)

Definition at line 19 of file cmdLineParser.c.

Specifies a command line argument that should be accepted by the program.

Parameters

[in]	longOption	The long name of option i.e., –optionname
[in]	shortOption	The short name of option i.e., -o
[in]	has_arg	Whether this option has an argument i.e., -o value. If has_arg is 0, then dataPtr must be an integer pointer.
[in]	type	The type of the argument. Valid values are: i integer f float d double s string c character
[in]	dataPtr	A pointer to where the value will be stored.
[in]	dataSize	The length of dataPtr, only useful for character strings.
[in]	help	A short help string, preferably a single line or less.
