char * value;
rle_hdr * the_hdr;
char * rle_getcom( name, the_hdr )

DESCRIPTION
Rle_putcom can be used to add a picture comment or change
the value of a picture comment in a rle_hdr(3) structure.
The argument value is the string value of the comment, and
is generally of the form name=value. It may also be of the
form name. If there is another comment with the same name,
it will be replaced with the new value, and the previous
comment will be returned as the value of rle_putcom.
Rle_getcom returns a pointer to the data portion of a
picture comment from an RLE file. The comment is assumed to
be in the form name=value; a pointer to value is returned.
If the comment is of the form name, a pointer to the null
character at the end of the string is returned. If there is
no comment of the above forms, a NULL pointer is returned.
The the_hdr structure contains the picture comments in
question.
Rle_delcom is used to delete a picture comment from a
rle_hdr(3) structure. It is called with the name of the
comment and the the_hdr structure to be modified. The first
comment in the rle_hdr structure of the form name=value or
name will be deleted. The deleted comment will be returned
as the function value.
