.SH "DESCRIPTION"
.PP
\fBglGetObjectLabel\fR
retrieves the label of the object identified by
\fIname\fR
within the namespace given by
\fIidentifier\fR\&.
\fIidentifier\fR
must be one of
\fBGL_BUFFER\fR,
\fBGL_SHADER\fR,
\fBGL_PROGRAM\fR,
\fBGL_VERTEX_ARRAY\fR,
\fBGL_QUERY\fR,
\fBGL_PROGRAM_PIPELINE\fR,
\fBGL_TRANSFORM_FEEDBACK\fR,
\fBGL_SAMPLER\fR,
\fBGL_TEXTURE\fR,
\fBGL_RENDERBUFFER\fR,
\fBGL_FRAMEBUFFER\fR, to indicate the namespace containing the names of buffers, shaders, programs, vertex array objects, query objects, program pipelines, transform feedback objects, samplers, textures, renderbuffers and frame buffers, respectively\&.
.PP
\fIlabel\fR
is the address of a string that will be used to store the object label\&.
\fIbufSize\fR
specifies the number of characters in the array identified by
\fIlabel\fR\&.
\fIlength\fR
contains the address of a variable which will receive the the number of characters in the object label\&. If
\fIlength\fR
is NULL, then it is ignored and no data is written\&. Likewise, if
\fIlabel\fR
is NULL, or if
\fIbufSize\fR
is zero then no data is written to
\fIlabel\fR\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_ENUM\fR
is generated if
\fIidentifier\fR
is not one of the accepted object types\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated if
\fIname\fR
is not the name of an existing object of the type specified by
\fIidentifier\fR\&.
.PP
\fBGL_INVALID_VALUE\fR
is generated if
\fIbufSize\fR
is zero\&.
.PP
If not NULL,
\fIlength\fR
and
\fIlabel\fR
should be addresses to which the client has write access, otherwise undefined behavior, including process termination may occur\&.
