Function Documentation

main()

int main	(	int	argc,
		char *	argv[] )

strip ANSI SGR sequences

Parameters

argc	Argument count (should be 2 for the program name and input file)
argv	Argument vector (argv[1] should be the input file name)

This function iterates through the input string, copying characters to the output buffer while skipping over any ANSI escape sequences. It looks for sequences that start with "\033[" and end with "m" or "K", and removes them from the output.

< Buffer to hold the input string read from the file

< Buffer to hold the cleaned output string
