interface C with Bash shell 1

[hectorDUQUE]

hi guys,
may somebody help me by privinding an example of an interface C-Bash shell ?

i mean, i can write a C program which runs a bash shell (using the system command), but how to get the answer ?

thanks in advance,

hector

FILE *fp = popen([red]"bash "[/red], "r" );
if ( fp != NULL ) {
  while ( fgets( buff, sizeof buff, fp ) != NULL ) {
  }
  pclose( fp );
}

Just replace the command with whatever bash command you have in mind, then read the result one line at a time, just like you would if you were reading a file.
