Function Details : wprintf

intwprintf(const wchar_t * format,... args) ;

Return Type : int

Integer type (typically 4 bytes, -2,147,483,648 to 2,147,483,647)
Read about return values of wprintf function .

1st Parameter Type : const wchar_t *

A pointer to a read-only wide-character string, where each character is of type `wchar_t`. Used for representing text in wide-character encoding to support extended character sets, such as Unicode. The string is null-terminated, with the terminator being a `wchar_t` with value 0.

1st Parameter

Pointer to a null-terminated wide-character string specifying the format of the output. It may include format specifiers like `%ls`, `%d`, etc.

2nd Parameter Type : ...

Represents a variable number of arguments in a function. Used in functions like `printf` or `fprintf` to accept additional parameters beyond those explicitly declared.

2nd Parameter

Additional arguments providing the values to format and write according to the format string.

The wprintffunction in C language Prints formatted wide character output to the standard output.
wprintf writes the wide string pointed to by format to the standard output (stdout). If format includes format specifiers (beginning with %), the additional arguments following format are formatted and inserted in the resulting wide string replacing their respective specifiers.
The wprintffunction takes 2 parameters:
  • •
    const wchar_t * `format`: Pointer to a null-terminated wide-character string specifying the format of the output. It may include format specifiers like `%ls`, `%d`, etc.
  • •
    ... `args`: Additional arguments providing the values to format and write according to the format string.
Writes a formatted wide-character string to the standard output (`stdout`). Returns the number of wide characters written, or a negative value if an error occurs.
The wprintf function return value :
  • Returns the number of wide characters written, or a negative value if an error occurred

Output

This example demonstrates the basic usage of wprintf to print a wide character string and an integer.
