page: `docbook-to-man manpage.sgml > manpage.1'. You may view
the manual page with: `docbook-to-man manpage.sgml | nroff -man |
less'. A typical entry in a Makefile or Makefile.am is:
manpage.1: manpage.sgml

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>Converts a data field as it stored in the database file into
a bcd string. The string will not be longer than 20 chars including
the final 0. It contains only the characters `+', `-', `0-9', and `.'.
You should use this function
instead of accessing the data directly.</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. <option>len</option> is the number of digits after the decimal
point.</para>
<para>The function allocates memory for the string returned in
<option>*value</option>. This memory has to be freed by the application.
</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>
