Description

Declares t_filenm for old-style command-line parsing of file name options.

Classes

#define	opt2FILE(opt, nfile, fnm, mode)   gmx_ffopen(opt2fn(opt, nfile, fnm), mode)
	Returns a file pointer from the filename.
#define	ftp2FILE(ftp, nfile, fnm, mode)   gmx_ffopen(ftp2fn(ftp, nfile, fnm), mode)
	Returns a file pointer from the file type.

Functions
const char *	opt2fn (const char *opt, int nfile, const t_filenm fnm[])
	Returns the filename belonging to cmd-line option opt, or NULL when no such option.
gmx::ArrayRef< const std::string >	opt2fns (const char *opt, int nfile, const t_filenm fnm[])
	Returns the filenames belonging to cmd-line option opt. More...
gmx::ArrayRef< const std::string >	opt2fnsIfOptionSet (const char *opt, int nfile, const t_filenm fnm[])
	Returns the filenames belonging to cmd-line option opt when set, returns an empty vector when the option is not set. More...
const char *	ftp2fn (int ftp, int nfile, const t_filenm fnm[])
	Returns the first file name with type ftp, or NULL when none found.
gmx::ArrayRef< const std::string >	ftp2fns (int ftp, int nfile, const t_filenm fnm[])
	Returns the filenames for the first option with type ftp. More...
bool	ftp2bSet (int ftp, int nfile, const t_filenm fnm[])
	Returns TRUE when this file type has been found on the cmd-line.
bool	opt2bSet (const char *opt, int nfile, const t_filenm fnm[])
	Returns TRUE when this option has been found on the cmd-line.
const char *	opt2fn_null (const char *opt, int nfile, const t_filenm fnm[])
	Returns the file name belonging top cmd-line option opt, or NULL when no such option. More...
const char *	ftp2fn_null (int ftp, int nfile, const t_filenm fnm[])
	Returns the first file name with type ftp, or NULL when none found. More...
bool	is_optional (const t_filenm *fnm)
	Returns whether or not this filenm is optional.
bool	is_output (const t_filenm *fnm)
	Returns whether or not this filenm is output.
bool	is_set (const t_filenm *fnm)
	Returns whether or not this filenm is set.
bool	hasSuffixFromNoAppend (std::string_view filename)
	Return whether filename might have been produced by mdrun -noappend. More...
int	add_suffix_to_output_names (t_filenm *fnm, int nfile, const char *suffix)
	When we do checkpointing, this routine is called to check for previous output files and append a '.partNNNN' suffix before the (output) file extensions. If there was already a '.partNNNN' suffix before the file extension, that is removed before the new suffix is added.
