NAME¶

std::fputs - std::fputs

Synopsis¶

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
