Function Documentation

Compress()

char * Compress ( const char * str )

extern

Remove all blanks from the string str.

The returned string has to be deleted by the user.

Definition at line 2579 of file TString.cxx.

EscChar()

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

extern

Escape specchars in src with escchar and copy to dst.

Definition at line 2600 of file TString.cxx.

Form()

char * Form ( const char * fmt, ... )

extern

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.
