NAME

RB_Find_Marker -- Search for header marker in document.

FUNCTION

Read document file line by line, and search each line for any of the headers defined in the array header_markers (OR if using the -rh switch, robo_head)

SYNOPSIS

static struct RB_HeaderType *RB_Find_Marker(
    FILE *document,
    int *is_internal,
    int reuse_previous_line )

INPUTS

document - pointer to the file to be searched. the gobal buffer line_buffer.

OUTPUT

document will point to the line after the line with the header marker.
is_internal will be TRUE if the header is an internal header.

RESULT

header type

BUGS

Bad use of feof(), fgets().
