19 | SYNOPSIS |
---|
20 | #include <stdio.h> |
---|
21 | #include <stdarg.h> |
---|
22 | int diprintf(int <[fd]>, const char *<[format]>, ...); |
---|
23 | int vdiprintf(int <[fd]>, const char *<[format]>, va_list <[ap]>); |
---|
24 | int _diprintf_r(struct _reent *<[ptr]>, int <[fd]>, |
---|
25 | const char *<[format]>, ...); |
---|
26 | int _vdiprintf_r(struct _reent *<[ptr]>, int <[fd]>, |
---|
27 | const char *<[format]>, va_list <[ap]>); |
---|
28 | |
---|
29 | DESCRIPTION |
---|
30 | <<diprintf>> and <<vdiprintf>> are similar to <<dprintf>> and <<vdprintf>>, |
---|
31 | except that only integer format specifiers are processed. |
---|
32 | |
---|
33 | The functions <<_diprintf_r>> and <<_vdiprintf_r>> are simply |
---|
34 | reentrant versions of the functions above. |
---|
35 | |
---|
36 | RETURNS |
---|
37 | Similar to <<dprintf>> and <<vdprintf>>. |
---|
38 | |
---|
39 | PORTABILITY |
---|
40 | This set of functions is an integer-only extension, and is not portable. |
---|
41 | |
---|
42 | Supporting OS subroutines required: <<sbrk>>, <<write>>. |
