Function Details : btowc

wint_tbtowc(int c) ;

Return Type : wint_t

An integer type capable of storing any wide character value or the special value WEOF, used in wide-character input/output functions.
Read about return values of btowc function .

1st Parameter Type : int

Integer type (typically 4 bytes, -2,147,483,648 to 2,147,483,647)

1st Parameter

A single-byte character to be converted to a wide character, or EOF

The btowcfunction in C language Converts a single-byte character to a wide character.
The btowc function determines the wide character corresponding to c, if c is a valid single-byte character in the initial shift state. This function is useful when working with mixed single-byte and wide character strings. It's important to note that this function is affected by the LC_CTYPE category of the current locale.
The btowcfunction takes 1 parameter:
  • •
    int `c`: A single-byte character to be converted to a wide character, or EOF
Converts a single-byte character to a wide character. If the input character is valid, the corresponding wide character is returned. If the input is EOF or invalid, `WEOF` is returned.
The btowc function return value :
  • Returns the wide character corresponding to c if c is a valid single-byte character in the initial shift state
  • If c is EOF or if c is not a valid single-byte character in the initial shift state, the function returns WEOF

Output

This example demonstrates the basic usage of the `btowc` function to convert a single-byte character 'A' to its wide character equivalent.
