The name string assigned to the active resource identified by <parameter>index</parameter> is
|
|
returned as a null-terminated string in the character array whose address is given in <parameter>name</parameter>. The actual number of
|
|
characters written into <parameter>name</parameter>, excluding the null terminator, is returned
|
|
in <parameter>length</parameter>. If <parameter>length</parameter> is NULL, no length is returned. The maximum
|
|
number of characters that may be written into <parameter>name</parameter>, including the null
|
|
terminator, is specified by <parameter>bufSize</parameter>. If the length of the name string
|
|
<emphasis>including the null terminator</emphasis> is greater than <parameter>bufSize</parameter>, the first
|
|
<parameter>bufSize</parameter>-1 characters of the name string will be written to <parameter>name</parameter>,
|
|
followed by a null terminator. If <parameter>bufSize</parameter> is zero, no error will be
|
|
generated but no characters will be written to <parameter>name</parameter>. The length of the
|
|
longest name string for <parameter>programInterface</parameter>>, including a null terminator,
|
|
can be queried by calling <citerefentry><refentrytitle>glGetProgramInterface</refentrytitle></citerefentry> with a <parameter>pname</parameter> of
