ASCIIToHex()

BYTE ASCIIToHex ( const CHAR ascii )

inline

Converts ASCII char to hexadecimal.

Parameters

[in]

ascii

- ASCII char to convert

Returns

Hexadecimal value

Here is the caller graph for this function:

HexToASCII()

CHAR HexToASCII ( const BYTE hex )

inline

Converts hexadecimal value to ASCII.

Parameters

[in]

hex

- Hexadecimal value to convert

Returns

ASCII char

isAlpha()

BOOL isAlpha ( const CHAR ascii )

inline

test for alphabetic char

Parameters

[in]

ascii

- ASCII char to check

Returns

true if alphabetic, false otherwise

Here is the call graph for this function:

Here is the caller graph for this function:

isAlphaNum()

BOOL isAlphaNum ( const CHAR ascii )

inline

test for alphanumeric char

Parameters

[in]

ascii

- ASCII char to check

Returns

true if alpha/numeric, false otherwise

Here is the call graph for this function:

isLowerCase()

BOOL isLowerCase ( const CHAR ascii )

inline

test for lower case alphabetic char

Parameters

[in]

ascii

- ASCII char to check

Returns

true if lower case, false otherwise

Warning

You probably should ensure ascii is alphabetic char first (false will be always returned in case non alphabetic char)

Here is the caller graph for this function:

isNum()

BOOL isNum ( const CHAR ascii )

inline

test for numeric char

Parameters

[in]

ascii

- ASCII char to check

Returns

true if numeric, false otherwise

Here is the caller graph for this function:

isUpperCase()

BOOL isUpperCase ( const CHAR ascii )

inline

test for upper case alphabetic char

Parameters

[in]

ascii

- ASCII char to check

Returns

true if upper case, false otherwise

Warning

You probably should ensure ascii is alphabetic char first (false will be always returned in case non alphabetic char)

Here is the caller graph for this function:

strDecToInt()

DWORD strDecToInt ( const CHAR *const pASCII, const BYTE len )

inline

ASCII decimal string to 32bit unsigned integer.

Parameters

[in]	pASCII	- pointer to ASCII string
[in]	len	- ASCII string length (max shall be 10, and may overflow return value when 10)

Returns

Unsigned integer value

Here is the call graph for this function:

strHexToInt()

DWORD strHexToInt ( const CHAR *const pASCII, const BYTE len )

inline

ASCII hexadecimal string to 32bit unsigned integer.

Parameters

[in]	pASCII	- pointer to ASCII string
[in]	len	- ASCII string length (max shall be 8)

Returns

Unsigned integer value

Here is the call graph for this function:

toLowerCase()

CHAR toLowerCase ( const CHAR ascii )

inline

Convert upper case alphabetic char to lower case.

Parameters

[in]

ascii

- ASCII char to convert

Returns

Lower case char, same value otherwise

Warning

You probably should ensure ascii is alphabetic char first

Here is the call graph for this function:

toUpperCase()

CHAR toUpperCase ( const CHAR ascii )

inline

Parameters

[in]

ascii

- ASCII char to convert

Returns

Upper case char, same value otherwise
