.SH "DESCRIPTION"
.PP
\fBglGetProgramPipelineiv\fR
retrieves the value of a property of the program pipeline object
\fIpipeline\fR\&.
\fIpname\fR
specifies the name of the parameter whose value to retrieve\&. The value of the parameter is written to the variable whose address is given by
\fIparams\fR\&.
.PP
If
\fIpname\fR
is
\fBGL_ACTIVE_PROGRAM\fR, the name of the active program object of the program pipeline object is returned in
\fIparams\fR\&.
.PP
If
\fIpname\fR
is
\fBGL_VERTEX_SHADER\fR, the name of the current program object for the vertex shader type of the program pipeline object is returned in
\fIparams\fR\&.
.PP
If
\fIpname\fR
is
\fBGL_TESS_CONTROL_SHADER\fR, the name of the current program object for the tessellation control shader type of the program pipeline object is returned in
\fIparams\fR\&.
.PP
If
\fIpname\fR
is
\fBGL_TESS_EVALUATION_SHADER\fR, the name of the current program object for the tessellation evaluation shader type of the program pipeline object is returned in
\fIparams\fR\&.
.PP
If
\fIpname\fR
is
\fBGL_GEOMETRY_SHADER\fR, the name of the current program object for the geometry shader type of the program pipeline object is returned in
\fIparams\fR\&.
.PP
If
\fIpname\fR
is
\fBGL_FRAGMENT_SHADER\fR, the name of the current program object for the fragment shader type of the program pipeline object is returned in
\fIparams\fR\&.
.PP
If
\fIpname\fR
is
\fBGL_INFO_LOG_LENGTH\fR, the length of the info log, including the null terminator, is returned in
\fIparams\fR\&. If there is no info log, zero is returned\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_OPERATION\fR
is generated if
\fIpipeline\fR
is not zero or a name previously returned from a call to
\fBglGenProgramPipelines\fR()
or if such a name has been deleted by a call to
\fBglDeleteProgramPipelines\fR()\&.
.PP
\fBGL_INVALID_ENUM\fR
is generated if
\fIpname\fR
is not one of the accepted values\&.
