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::fer- ror) 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 See also printf fprintf prints formatted output to stdout, a file stream or a buffer sprintf (function) snprintf (C++11) puts writes a character string to stdout (function) fputws writes a wide string to a file stream (function) fgets gets a character string from a file stream (function) http://cppreference.com 2022.07.31 std::fputs(3)
