# std::fputs

From cppreference.com
< cpp‎ | io‎ | c

Defined in header `<cstdio>` |  |
int fputs( const char* str, std::FILE* stream ); |  |

Writes every character from the null-terminated string `str` to the output stream `stream`, as if by repeatedly executing std::fputc.

The terminating null character from `str` is not written.

### Parameters

str | - | null-terminated character string to be written
stream | - | output stream

### Return value

On success, returns a non-negative value

On failure, returns EOF and sets the error indicator (see std::ferror) on `stream`.

### Notes

The related function std::puts appends a newline character to the output, while `std::fputs` writes the string unmodified.

Different implementations return different non-negative numbers: some return the last character written, some return the number of characters written (or INT_MAX if the string was longer than that), some simply return a non-negative constant such as zero.

### Example

Run this code

    #include <cstdio>

    int main(void)
    {
        int rc = std::fputs("Hello World", stdout);

        if (rc == EOF)
           std::perror("fputs()"); // POSIX requires that errno is set
    }

Output:

    Hello World
