Function Documentation

Compress()

char * Compress

(

const char *

str

)

Remove all blanks from the string str.

The returned string has to be deleted by the user.

Definition at line 2479 of file TString.cxx.

EscChar()

int EscChar	(	const char *	src,
		char *	dst,
		int	dstlen,
		char *	specchars,
		char	escchar
	)

Escape specchars in src with escchar and copy to dst.

Definition at line 2500 of file TString.cxx.

Form()

char * Form	(	const char *	va_fmt,
			...
	)

Formats a string in a circular formatting buffer.

Removes the need to create and delete short lived strings. Don't pass Form() pointers from user code down to ROOT functions as the circular buffer may be overwritten downstream. Use Form() results immediately or use TString::Format() instead.

Definition at line 2397 of file TString.cxx.

static char * Format ( const char *  format, va_list  ap  )

static

Format a string in a circular formatting buffer (using a printf style format descriptor).
