Assuming hw.awk contains: |

<lang awk>BEGIN \ |

{ |
|||
printf( "Hello, World!\n" ); |
|||
} # BEGIN</lang> |
|||
_hw_awk.c would contani: |
|||
<lang c>#include <stdio.h> |
|||
#include <errno.h> |
|||
static void w( char * line, FILE * tf ) |
|||
{fputs( line, tf ); |
|||
if( errno != 0 ){ perror( "temp" );exit( 2 ); } |

} |

int main( int argc, char ** argv ) |

{FILE * tf = fopen( "/tmp/t", "w" ); |

if( tf == NULL ){ perror( "temp" );exit( 1 ); } |

w( "{\n", tf ); |

w( " printf( \"Hello, World!\\n\" );\n", tf ); |
