Can anyone tell what happens if each end writes at the same time on the same socket ?
- if one of them issues a read() after write() has completed, will it record into the buffer what the other sent ?
ex.

ra_rgbe
RA_RGBE(1) General Commands Manual RA_RGBE(1)NAME
ra_rgbe - convert between different RADIANCE picture types
SYNOPSIS
ra_rgbe [ -r ][ -e +/-stops ][ -f ][ -n frameno ] [ input [ outspec ] ]
DESCRIPTION
Ra_rgbe converts between RADIANCE run-length encoded and flat formats, and separates concatanated animation frames produced by rpict(1).
The -e option specifies an exposure compensation in f-stops (powers of two). Only integer stops are allowed, for efficiency. By default,
ra_rgbe produces a flat RADIANCE picture file from any type of RADIANCE input picture. The -r option causes ra_rgbe to produce a run-
length encoded file instead.
If the input file consists of multiple animation frames as produced by rpict with the -S option, ra_rgbe will read each frame and write it
to the output file created by calling printf(3) with the output specification and frame number as arguments. If the output specification
begins with an exclamation mark ('!'), then this interpreted as a command spec., which is also run through printf with the frame number to
get the final command. This command must accept a Radiance picture on its standard input, and may write results either to a file or to the
standard output. The -n option may be used to select a specific frame for output, and other frames in the input will be skipped. Nor-
mally, all frames will be read and written.
Ra_rgbe will report an error and exit if the target output file already exists, unless the -f option is given. If the output file is miss-
ing, the standard output is used. If the input file is missing or set to '-', the standard input is used.
NOTES
The file format for RADIANCE pictures was changed between release 1.4 and release 2.0. The older format can still be read by all the pro-
grams, but only the newer format is produced. This newer format cannot be read by RADIANCE software prior to release 2.0.
Ra_rgbe provides some downward compatibility by producing files that can be read by older RADIANCE software. The resultant files are also
easier to manipulate with programs designed to read raw raster data.
The other use for ra_rgbe is as a quicker way to adjust the exposure of a RADIANCE picture than pfilt(1), since ra_rgbe only allows integer
f-stop changes. In this mode, ra_rgbe should be used with the -r option.
