Next: Interrupts and Signals Up: Piping in a C program Previous: popen() - Formatted Piping . int pipe(int fd[2]) - creates a pipe and returns two file descriptors, fd[0], fd[1] . fd[0] is opened for reading, fd[1] for writing. pipe() returns 0 on success, -1 on failure and sets errno accordingly. ... Pipes opened with pipe() should be closed with close(int fd) . ... An example of piping in a C program is plot.c and subroutines and is detailed in Appendix . ...

... This method has no equal as of its versatility and short observation times. ... First observations were made on RATAN-600 with a unique MARS-3 16-channel (32 inputs) Matrix Radiometric System that has no analogue in Russian radio astronomy. ... Centre for Analysis of Multiwave Observations Created on RATAN-600. An on-line processing centre for analysis of multiwave radio observations of the Sun on RATAN-600 was created in the St.Petersburg Branch of SAO RAS, see http://www.spbf.sao.ru/prognoz/ . ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...
