std::fputs
From cppreference.com
| 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
