.SH "NAME"
glIsShader \- Determines if a name corresponds to a shader object
.SH "C SPECIFICATION"
.HP \w'GLboolean\ glIsShader('u
.BI "GLboolean glIsShader(GLuint\ " "shader" ");"
.SH "PARAMETERS"
.PP
\fIshader\fR
.RS 4
Specifies a potential shader object\&.
.RE
.SH "DESCRIPTION"
.PP
\fBglIsShader\fR
returns
\fBGL_TRUE\fR
if
\fIshader\fR
is the name of a shader object previously created with
\fBglCreateShader\fR()
and not yet deleted with
\fBglDeleteShader\fR()\&. If
\fIshader\fR
is zero or a non\-zero value that is not the name of a shader object, or if an error occurs,
\fBglIsShader \fR
returns
\fBGL_FALSE\fR\&.
.SH "NOTES"
.PP
No error is generated if
\fIshader\fR
is not a valid shader object name\&.
.PP
A shader object marked for deletion with
\fBglDeleteShader\fR()
but still attached to a program object is still considered a shader object and
\fBglIsShader\fR
will return
\fBGL_TRUE\fR\&.
.SH "ASSOCIATED GETS"
.PP
\fBglGetAttachedShaders\fR()
with a valid program object
.PP
\fBglGetShader\fR()
with arguments
\fIshader\fR
and a parameter to be queried

\fBglGetShaderInfoLog\fR()
