fputs - cppreference.com (original) (raw)

| Defined in header <stdio.h> | | | | --------------------------------------------------------------------------------------------------------------------------------- | | ----------- | | int fputs( const char* str, FILE* stream ); | | (until C99) | | int fputs( const char* restrict str, FILE* restrict stream ); | | (since C99) |

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

The terminating null character from str is not written.

[edit] Parameters

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

[edit] Return value

On success, returns a non-negative value.

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

[edit] Notes

The related function puts appends a newline character to the output, while 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.

[edit] Example

#include <stdio.h> int main(void) { int rc = fputs("Hello World", stdout); if (rc == EOF) perror("fputs()"); // POSIX requires that errno is set }

Output:
