PUTS (3) \| C library functions \| Unix Manual Pages \| :man▋ NAME fputc, fputs, putc, putchar, puts - output of characters and strings CONTENTS Synopsis Description Bugs SYNOPSIS #include <stdio.h> "int fputc(int "c", FILE "stream); "int fputs(const char "*"s"", FILE "**"stream"); "int putc(int "c", FILE "stream); "int putchar(int "c); "int puts(const char "**"s"); DESCRIPTION fputc() writes the character c, cast to an "unsigned char", to stream. fputs() writes the string s to stream, without its trailing ’\0’. putc() is equivalent to fputc() except that it may be implemented as a macro which evaluates stream more than once. "putchar("c); is equivalent to "putc("c,stdout). puts() writes the string s and a trailing newline to stdout. Calls to the functions described here can be mixed with each other and with calls to other output functions from the stdio library for the same output stream. For non-locking counterparts, see unlocked_stdio(3). "RETURN VALUE" fputc()," putc() "and" putchar()" return the character written as an unsigned char cast to an int or EOF on error. puts()" and "fputs() return a non-negative number on success, or EOF on error. "CONFORMING TO" ANSI - C, POSIX.1 BUGS It is not advisable to mix calls to output functions from the stdio library with low - level calls to write() for the file descriptor associated with the same output stream; the results will be undefined and very probably not what you want. "SEE ALSO" write(2), ferror(3), fopen(3), fseek(3), fwrite(3), gets(3), scanf(3), unlocked_stdio(3)
