int compat_mkdir

(

const char *

newDir

)

[inline]

Create a directory.

int compat_rename	(	const char *	src,
		const char *	dst
	)			[inline]

Rename a file.

Mingw does provide rename(), but gives an error if the destination name already exists. This one doesn't.

bool compat_setenv	(	const char *	name,
		const char *	value
	)			[inline]

Set/overwrite environment variable, return SUCCESS or FAILURE.

void compat_swapFileUriChars

(

string &

s

)

[inline]

(For "file:" URI handling) If directory separator on this system is not '/', exchange the actual separator for '/' and vice versa in the supplied string.

Do the same for any non-'.' file extension separator. We trust in the optimizer to remove unnecessary code.

int compat_truncate	(	const char *	path,
		uint64	length
	)			[inline]

Truncate a file to a given length.

Behaviour undefined if given length is bigger than current file size

int ttyWidth

(

)

Width in characters of the tty (for progress display), or 0 if not a tty or functions not present on system.
