[comp.windows.x] placing the output of a command in a text widget

kjh@visual1.jhuapl.edu (Kenneth J. Heeres) (03/20/91)

I would like to be able to issue a shell command and capture the
output for use in a text widget.  I have written  code that takes
a file descripter and passes the contents of the file to the
text widget.  I tried using popen to capture the output.  My
code counts the characters in the file descriptor, allocates the
space, rewinds the file, and then reads it into the space.  The
rewind on the pipe from popen gives an error.  Indicating illegal
seek??  Any help?
