Function Documentation

◆ uAscii2Hex()

unsigned char UTILITE_EXPORT 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
cthe ascii character
Returns
the hexadecimal value

Definition at line 288 of file UConversion.cpp.

◆ uBool2Str()

std::string UTILITE_EXPORT uBool2Str ( bool  boolean)

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

Parameters
booleanthe boolean to convert in a string
Returns
the string

Definition at line 156 of file UConversion.cpp.

◆ uBytes2Hex()

std::string UTILITE_EXPORT 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
bytesthe bytes array
bytesLenthe length of the bytes array
Returns
the hexadecimal string

Definition at line 203 of file UConversion.cpp.

◆ uBytes2Str()

std::string UTILITE_EXPORT 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
bytesthe array of bytes
Returns
the string

Definition at line 188 of file UConversion.cpp.

◆ uFormat()

std::string UTILITE_EXPORT 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_EXPORT 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_EXPORT 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
cthe hexadecimal value
rightPartIf 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_EXPORT 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
hexthe hexadecimal string
bytesLenthe hexadecimal string length
Returns
the bytes array

Definition at line 228 of file UConversion.cpp.

◆ uHex2Bytes() [2/2]

std::vector<char> UTILITE_EXPORT 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
hexthe hexadecimal string
Returns
the bytes array

Definition at line 223 of file UConversion.cpp.

◆ uHex2Str()

std::string UTILITE_EXPORT 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
hexthe hexadecimal string
Returns
the ascii string

Definition at line 250 of file UConversion.cpp.
