Function Documentation

◆ uAscii2Hex()

unsigned char UTILITE_EXP uAscii2Hex ( const unsigned char & c )

Convert an ascii character to an hexadecimal value (right 4 bits). Characters can be in upper or lower case. Example :

unsigned char hex = uAscii2Hex('F');

// The results is hex = 0x0F;

See also: hex2ascii

Parameters

c	the ascii character

Returns: the hexadecimal value

Definition at line 288 of file UConversion.cpp.

◆ uBool2Str()

std::string UTILITE_EXP uBool2Str ( bool boolean )

Convert a bool to a string. The format used is "true" and "false".

Parameters

boolean the boolean to convert in a string

Returns: the string

Definition at line 156 of file UConversion.cpp.

◆ uBytes2Hex()

std::string UTILITE_EXP uBytes2Hex	(	const char *	bytes,
		unsigned int	bytesLen
	)

Convert a bytes array to an hexadecimal string. The resulting string is twice the size of the bytes array. The hexadecimal Characters are in upper case. Example :

char bytes[] = {0x3F};
std::string hex = uBytes2Hex(bytes, 1);
// The string constains "3F".

Parameters

bytes	the bytes array
bytesLen	the length of the bytes array

Returns: the hexadecimal string

Definition at line 203 of file UConversion.cpp.

◆ uBytes2Str()

std::string UTILITE_EXP uBytes2Str ( const std::vector< unsigned char > & bytes )

Convert an array of bytes to string, the array of bytes must end with the null character ('\0').

Parameters

bytes the array of bytes

Returns: the string

Definition at line 188 of file UConversion.cpp.

◆ uFormat()

std::string UTILITE_EXP uFormat	(	const char *	fmt,
			...
	)

Format a string like printf, and return it as a std::string

Definition at line 365 of file UConversion.cpp.

◆ uFormatv()

std::string UTILITE_EXP uFormatv	(	const char *	fmt,
		va_list	ap
	)

Format a string like printf, and return it as a std::string

Definition at line 322 of file UConversion.cpp.

◆ uHex2Ascii()

unsigned char UTILITE_EXP uHex2Ascii	(	const unsigned char &	c,
		bool	rightPart
	)

Convert hexadecimal (left or right part) value to an ascii character. Example :

unsigned char F = uHex2Ascii(0xFA, false);

unsigned char A = uHex2Ascii(0xFA, true);

See also: ascii2hex

Parameters

c	the hexadecimal value
rightPart	If we want the character corresponding to the right of left part (4 bits) of the byte value.

Returns: the ascii character (in upper case)

Definition at line 276 of file UConversion.cpp.

◆ uHex2Bytes() [1/2]

std::vector<char> UTILITE_EXP uHex2Bytes ( const std::string & hex )

Convert an hexadecimal string to a bytes array. The string must be pair length. The hexadecimal Characters can be in upper or lower case. Example :

std::string hex = "1f3B";
std::vector<char> bytes = uHex2Bytes(hex);
// The array contains {0x1F, 0x3B}.

Parameters

hex	the hexadecimal string

Returns: the bytes array

Definition at line 223 of file UConversion.cpp.

◆ uHex2Bytes() [2/2]

std::vector<char> UTILITE_EXP uHex2Bytes	(	const char *	hex,
		int	hexLen
	)

Convert an hexadecimal string to a bytes array. The string must be pair length. The hexadecimal Characters can be in upper or lower case. Example :

std::vector<char> bytes = uHex2Bytes("1f3B", 4);

// The array contains {0x1F, 0x3B}.

Parameters

hex	the hexadecimal string
bytesLen	the hexadecimal string length

Returns: the bytes array

Definition at line 228 of file UConversion.cpp.

◆ uHex2Str()

std::string UTILITE_EXP uHex2Str ( const std::string & hex )

Convert an hexadecimal string to an ascii string. A convenient way when using only strings. The hexadecimal str MUST not contains any null values 0x00 ("00"). Think to use of hex2bytes() to handle 0x00 values. Characters can be in upper or lower case. Example :

std::string str = uHex2Str("48656C6C4F21");

// The string contains "Hello!".

See also: hex2bytes

Parameters

hex	the hexadecimal string

Returns: the ascii string
