Function Documentation

LongBit()

size_t LongBit ( )

inline

Definition at line 61 of file scanutils.cpp.

                        {
  return CHAR_BIT * sizeof(long);
}

tfscanf()

int tfscanf	(	FILE *	stream,
		const char *	format,
			...
	)

fscanf variant to ensure correct reading regardless of locale.

tfscanf parse a file stream according to the given format. See the fscanf manpage for more information, as this function attempts to mimic its behavior.

Note

Note that scientific floating-point notation is not supported.
