| FUNCTION |
| <<fputc>>---write a character on a stream or file |
| |
| INDEX |
| fputc |
| INDEX |
| _fputc_r |
| |
| ANSI_SYNOPSIS |
| #include <stdio.h> |
| int fputc(int <[ch]>, FILE *<[fp]>); |
| |
| #include <stdio.h> |
| int _fputc_r(struct _rent *<[ptr]>, int <[ch]>, FILE *<[fp]>); |
| |
| TRAD_SYNOPSIS |
| #include <stdio.h> |
| int fputc(<[ch]>, <[fp]>) |
| int <[ch]>; |
| FILE *<[fp]>; |
| |
| #include <stdio.h> |
| int _fputc_r(<[ptr]>, <[ch]>, <[fp]>) |
| struct _reent *<[ptr]>; |
| int <[ch]>; |
| FILE *<[fp]>; |
| |
| DESCRIPTION |
| <<fputc>> converts the argument <[ch]> from an <<int>> to an |
| <<unsigned char>>, then writes it to the file or stream identified by |
| <[fp]>. |
| |
| If the file was opened with append mode (or if the stream cannot |
| support positioning), then the new character goes at the end of the |
| file or stream. Otherwise, the new character is written at the |
| current value of the position indicator, and the position indicator |
| oadvances by one. |
| |
| For a macro version of this function, see <<putc>>. |
| |
| The <<_fputc_r>> function is simply a reentrant version of <<fputc>> |
| that takes an additional reentrant structure argument: <[ptr]>. |
| |
| RETURNS |
| If successful, <<fputc>> returns its argument <[ch]>. If an error |
| intervenes, the result is <<EOF>>. You can use `<<ferror(<[fp]>)>>' to |
| query for errors. |
| |
| PORTABILITY |
| <<fputc>> is required by ANSI C. |
| |
| Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>, |
| <<lseek>>, <<read>>, <<sbrk>>, <<write>>. |
