RLE_PUTCOM(3)		   Library Functions Manual		 RLE_PUTCOM(3)

NAME
       rle_putcom - set	the value of a picture comment in an RLE file.
       rle_getcom - get	a picture comment from an RLE file.
       rle_delcom - delete a picture comment from an RLE file.

SYNOPSIS
       #include	<rle.h>

       char * rle_putcom( value, the_hdr )
       char * value;
       rle_hdr * the_hdr;

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

       char * rle_delcom( name,	the_hdr	)
       char * name;
       rle_hdr * 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)	struc-
       ture.  It is called with	the name of the	comment	and the	the_hdr	struc-
       ture 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.
