page: `docbook-to-man manpage.sgml > manpage.1'. You may view
the manual page with: `docbook-to-man manpage.sgml | nroff -man |

The docbook-to-man binary is found in the docbook-to-man package.
Please remember that if you create the nroff version in one of the
debian/rules file targets (such as build), you will need to include
docbook-to-man in your Build-Depends control field.

<title>DESCRIPTION</title>
<para>Reads a graphic data field. This function may be used only for
blobs of type pxfGraphic.</para>
<para><option>data</option> points to the start of the data field in the
record. It must be calculated by summing up all field length before
the field to operate on and add it to the base pointer of the
record. You should use this function instead of accessing the data
directly.</para>
<para>&funcname; returns blob data stored in the record itself, or in
an MB files which must have been set with
<function>PX_set_blob_file(3)</function>.</para>
<para>The function allocates memory for the data returned in
<option>*value</option>. This memory has to be freed by the application.
The amount of memory for the blob is returned in
<option>*blobsize</option>. <option>*mod</option> returns the so called
modification number of the blob which can often be used as an unique
id for creating file names, if the data is saved in a file.
</para>
<note><para>This function is deprecated and obsolete if
<function>PX_retrieve_record(3)</function> is used.</para></note>

<title>RETURN VALUE</title>
<para>Returns 0 if the value is NULL, -1 in case of an error and 1
otherwise.</para>
