Function Documentation

U64 str_to_U64 ( const std::string &  str  ) 

Forgivingly parse a null terminated character array.

Parameters:
str The string to parse.
Returns:
Returns the first U64 value found in the string or 0 on failure.
char* U64_to_str ( U64  value,
char *  result,
S32  result_size 
)

Given a U64 value, return a printable representation.

The client of this function is expected to provide an allocated buffer. The function then snprintf() into that buffer, so providing NULL has undefined behavior. Providing a buffer which is too small will truncate the printable value, so usually you want to declare the buffer:

char result[U64_BUF]; std::cout << "value: " << U64_to_str(value, result, U64_BUF);

Parameters:
value The U64 to turn into a printable character array.
result The buffer to use
result_size The size of the buffer allocated. Use U64_BUF.
Returns:
Returns the result pointer.

Here is the call graph for this function:

std::string U64_to_str ( U64  value  ) 

Given a U64 value, return a printable representation.

Parameters:
value The U64 to turn into a printable character array.
Returns:
Returns the result string.
