DESCRIPTION
|
|
<<dprintf>> and <<vdprintf>> allow printing a format, similarly to
|
|
<<printf>>, but write to a file descriptor instead of to a <<FILE>>
|
|
stream.
|
|
|
|
The functions <<_dprintf_r>> and <<_vdprintf_r>> are simply
|
|
reentrant versions of the functions above.
|
|
|
|
RETURNS
|
|
The return value and errors are exactly as for <<write>>, except that
|
|
<<errno>> may also be set to <<ENOMEM>> if the heap is exhausted.
|
|
|
|
PORTABILITY
|
|
This function is originally a GNU extension in glibc and is not portable.
|
|
|
|
Supporting OS subroutines required: <<sbrk>>, <<write>>.
