std::fputs(3) C++ Standard Libary std::fputs(3)

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
