Functions
bool	Bond::IsAlnum (int c)
	Returns whether a character is an ASCII alphanumeric character (i.e. a decimal digit or an upper or lower case letter).
bool	Bond::IsAlpha (int c)
	Returns whether a character is an ASCII alphabetic character (i.e. an upper or lower case letter).
bool	Bond::IsBlank (int c)
	Returns whether a character is an ASCII blank character (i.e. a space or a horizontal tab).
bool	Bond::IsCntrl (int c)
	Returns whether a character is an ASCII control character (i.e. 0 through 31 or 127).
bool	Bond::IsDigit (int c)
	Returns whether a character is an ASCII decimal digit.
bool	Bond::IsGraph (int c)
	Returns whether a character is an ASCII character with a graphical representation (i.e. it is printable and is not a space).
bool	Bond::IsLower (int c)
	Returns whether a character is an ASCII lower case letter.
bool	Bond::IsPrint (int c)
	Returns whether a character is a printable ASCII character (i.e. a graphical character or a space).
bool	Bond::IsPunct (int c)
	Returns whether a character is an ASCII punctuation character (i.e. a graphical character that is not alphanumeric).
bool	Bond::IsSpace (int c)
	Returns whether a character is an ASCII whitespace character (i.e. a space, horizontal tab, newline, vertical tab, form feed or carriage return).
bool	Bond::IsUpper (int c)
	Returns whether a character is an ASCII upper case letter.
bool	Bond::IsXDigit (int c)
	Returns whether a character is an ASCII hexadecimal digit (i.e. the digits 0 through 9 and upper and lower case letters A through F).
int	Bond::ToLower (int c)
	Returns an ASCII upper case letter converted to lower case. If the given character is not an ASCII upper case letter, it is returned unchanged.
int	Bond::ToUpper (int c)
	Returns an ASCII lower case letter converted to upper case. If the given character is not an ASCII lower case letter, it is returned unchanged.

Detailed Description

Functions for classifying and converting characters.

Only ASCII characters (values 0 through 127) are classified. All other values, including the negative char values of the bytes of multi-byte UTF-8 sequences, are not members of any class and are returned unchanged by the conversion functions. The results do not depend on the locale.

Function Documentation

IsAlnum()

bool Bond::IsAlnum

(

int

c

)

Returns whether a character is an ASCII alphanumeric character (i.e. a decimal digit or an upper or lower case letter).

Parameters

c	The character to classify.

IsAlpha()

bool Bond::IsAlpha

(

int

c

)

Returns whether a character is an ASCII alphabetic character (i.e. an upper or lower case letter).

Parameters

c	The character to classify.

IsBlank()

bool Bond::IsBlank

(

int

c

)

Returns whether a character is an ASCII blank character (i.e. a space or a horizontal tab).

Parameters

c	The character to classify.

IsCntrl()

bool Bond::IsCntrl

(

int

c

)

Returns whether a character is an ASCII control character (i.e. 0 through 31 or 127).

Parameters

c	The character to classify.

IsDigit()

bool Bond::IsDigit

(

int

c

)

Returns whether a character is an ASCII decimal digit.

Parameters

c	The character to classify.

IsGraph()

bool Bond::IsGraph

(

int

c

)

Returns whether a character is an ASCII character with a graphical representation (i.e. it is printable and is not a space).

Parameters

c	The character to classify.

IsLower()

bool Bond::IsLower

(

int

c

)

Returns whether a character is an ASCII lower case letter.

Parameters

c	The character to classify.

IsPrint()

bool Bond::IsPrint

(

int

c

)

Returns whether a character is a printable ASCII character (i.e. a graphical character or a space).

Parameters

c	The character to classify.

IsPunct()

bool Bond::IsPunct

(

int

c

)

Returns whether a character is an ASCII punctuation character (i.e. a graphical character that is not alphanumeric).

Parameters

c	The character to classify.

IsSpace()

bool Bond::IsSpace

(

int

c

)

Returns whether a character is an ASCII whitespace character (i.e. a space, horizontal tab, newline, vertical tab, form feed or carriage return).

Parameters

c	The character to classify.

IsUpper()

bool Bond::IsUpper

(

int

c

)

Returns whether a character is an ASCII upper case letter.

Parameters

c	The character to classify.

IsXDigit()

bool Bond::IsXDigit
