Any conflict between the requirements described here and the +ISO\ C standard is unintentional. This volume of POSIX.1\(hy2017 defers to the ISO\ C standard. +.P +The +\fIfputc\fR() +function shall write the byte specified by +.IR c +(converted to an +.BR "unsigned char" ) +to the output stream pointed to by +.IR stream , +at the position indicated by the associated file-position indicator for +the stream (if defined), and shall advance the indicator appropriately. +If the file cannot support positioning requests, or if the stream was +opened with append mode, the byte shall be appended to the output +stream. +.P +The last data modification and last file status change timestamps +of the file shall be marked for update between the successful +execution of +\fIfputc\fR() +and the next successful completion of a call to +\fIfflush\fR() +or +\fIfclose\fR() +on the same stream or a call to +\fIexit\fR() +or +\fIabort\fR(). +.SH "RETURN VALUE" +Upon successful completion, +\fIfputc\fR() +shall return the value it has written. Otherwise, it shall return EOF, +the error indicator for the stream shall be set, +and +.IR errno +shall be set to indicate the error. +.SH ERRORS +The +\fIfputc\fR() +function shall fail if either the +.IR stream +is unbuffered or the +.IR stream 's +buffer needs to be flushed, and: +.TP +.BR EAGAIN +The O_NONBLOCK flag is set for the file descriptor underlying +.IR stream +and the thread would be delayed in the write operation. +.TP +.BR EBADF +The file descriptor underlying +.IR stream +is not a valid file descriptor open for writing. +.TP +.BR EFBIG +An attempt was made to write to a file that exceeds the maximum file +size. +.TP +.BR EFBIG +An attempt was made to write to a file that exceeds the file +size limit of the process. +.TP +.BR EFBIG +The file is a regular file and an attempt was made to write at or +beyond the offset maximum. +.TP +.BR EINTR +The write operation was terminated due to the receipt of a signal, and +no data was transferred. +.TP +.BR EIO +A physical I/O error has occurred, or the process is a member of a +background process group attempting to write to its controlling terminal, +TOSTOP is set, the calling thread is not blocking SIGTTOU, the process +is not ignoring SIGTTOU, and the process group of the process is orphaned. +This error may also be returned under implementation-defined conditions. +.TP +.BR ENOSPC +There was no free space remaining on the device containing the file. +.TP +.BR EPIPE +An attempt is made to write to a pipe or FIFO that is not open for +reading by any process. A SIGPIPE signal shall also be sent to the +thread. +.br +.P +The +\fIfputc\fR() +function may fail if: +.TP +.BR ENOMEM +Insufficient storage space is available. +.TP +.BR ENXIO +A request was made of a nonexistent device, or the request was +outside the capabilities of the device. +.LP +.IR "The following sections are informative." +.SH EXAMPLES +None. +.SH "APPLICATION USAGE" +None. +.SH RATIONALE +None. +.SH "FUTURE DIRECTIONS" +None. +.SH "SEE ALSO" +.IR "Section 2.5" ", " "Standard I/O Streams", +.IR "\fIferror\fR\^(\|)", +.IR "\fIfopen\fR\^(\|)", +.IR "\fIgetrlimit\fR\^(\|)", +.IR "\fIputc\fR\^(\|)", +.IR "\fIputs\fR\^(\|)", +.IR "\fIsetbuf\fR\^(\|)", +.IR "\fIulimit\fR\^(\|)" +.P +The Base Definitions volume of POSIX.1\(hy2017, +.IR "\fB<stdio.h>\fP" +.\" +.SH COPYRIGHT +Portions of this text are reprinted and reproduced in electronic form +from IEEE Std 1003.1-2017, Standard for Information Technology +-- Portable Operating System Interface (POSIX), The Open Group Base +Specifications Issue 7, 2018 Edition, +Copyright (C) 2018 by the Institute of +Electrical and Electronics Engineers, Inc and The Open Group. +In the event of any discrepancy between this version and the original IEEE and +The Open Group Standard, the original IEEE and The Open Group Standard +is the referee document.
