FPUTS(3) Library Functions Manual FPUTS(3) NAME fputs, fputs_unlocked, puts -- output a line to a stream LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <stdio.h> int fputs(const char *str, FILE *stream); int fputs_unlocked(const char *str, FILE *stream); int puts(const char *str); DESCRIPTION The function fputs() writes the string pointed to by str to the stream pointed to by stream. The fputs_unlocked() function is equivalent to fputs(), except that the caller is responsible for locking the stream with flockfile(3) before call- ing it. This function may be used to avoid the overhead of locking the stream and to prevent races when multiple threads are operating on the same stream. The function puts() writes the string str, and a terminating newline char- acter, to the stream stdout. RETURN VALUES The functions fputs() and puts() return a nonnegative integer on success and EOF on error. ERRORS [EBADF] The stream argument is not a writable stream. The functions fputs() and puts() may also fail and set errno for any of the errors specified for the routines write(2). SEE ALSO ferror(3), fputws(3), putc(3), stdio(3) STANDARDS The functions fputs() and puts() conform to ISO/IEC 9899:1990 ("ISO C90"). FreeBSD ports 15.1 January 23, 2020 FPUTS(3)
