Function Documentation

G_basename()

char* G_basename	(	char *	filename,
		const char *	desired_ext
	)

Truncates filename to the base part (before the last '.') if it matches the extension, otherwise leaves it unchanged.

Checks if a filename matches a certain file extension (case insensitive) and if so, truncates the string to the base file name (cf. basename Unix command)

Parameters

filename	string containing filename
desired_ext	string containing extension to look for (case insensitive)

Returns

pointer to filename

G_double_to_basename_format()

char* G_double_to_basename_format	(	double	number,
		size_t	ndigits,
		size_t	ndecimals
	)

Convert a double to a string substituting the dot with underscore 12.3456 => '12_3456'.

Parameters

number	the double number that will be converted to string
ndigits	the number of integer digits in the output string
ndecimals	the number of decimals in the output string

Returns

a formatted string

G_generate_basename()

char* G_generate_basename	(	const char *	basename,
		double	number,
		size_t	ndigits,
		size_t	ndecimals
	)

Generate the format string.

Parameters

basename	String with the basename
number	The double number that will be converted to string
ndigits	The number of integer digits in the output string
ndecimals	The number of decimals in the output string

Returns

Format string

G_join_basename_strings()

char* G_join_basename_strings	(	const char **	strings,
		size_t	len
	)

join an array of strings using the basename separator

Parameters

strings	is an array of strings
len	is the length of the array

Returns

a joined string
