* estream: Avoid calling write(fd,NULL,n).Werner Koch2015-10-181-20/+32
| | | | | | | | | | | | | | | * src/estream.c (es_func_fd_write): Take care of a flush requests. (es_func_w32_write): Ditto. (es_func_fp_write): Ditto. -- The write handlers may be called with (BUFFER,SIZE) of (NULL,0) to propagate flush events to user supplied functions (es_fopencookie). However we need to take care to also do this with the internal handler. Might be a reason for system faults due to write or fwrite with a NULL buffer; on Linux this seems to be harmless.

We may want to change them to inline functions, though. gpgrt_pending is changed to a macro with the idea that we eventually can export the samestream flags and thus avoid the function call overhead in the samethread case too.
