.PP
\fIshader\fR
.RS 4
Specifies the shader object to be queried\&.
.RE
.PP
\fIpname\fR
.RS 4
Specifies the object parameter\&. Accepted symbolic names are
\fBGL_SHADER_TYPE\fR,
\fBGL_DELETE_STATUS\fR,
\fBGL_COMPILE_STATUS\fR,
\fBGL_INFO_LOG_LENGTH\fR,
\fBGL_SHADER_SOURCE_LENGTH\fR\&.
.RE

\fIparams\fR
.RS 4
Returns the requested object parameter\&.
.RE
.SH "DESCRIPTION"
.PP
\fBglGetShader\fR
returns in
\fIparams\fR
the value of a parameter for a specific shader object\&. The following parameters are defined:
.PP
\fBGL_SHADER_TYPE\fR
.RS 4
\fIparams\fR
returns
\fBGL_VERTEX_SHADER\fR
if
\fIshader\fR
is a vertex shader object,
\fBGL_GEOMETRY_SHADER\fR
if
\fIshader\fR
is a geometry shader object, and
\fBGL_FRAGMENT_SHADER\fR
if
\fIshader\fR
is a fragment shader object\&.
.RE
.PP
\fBGL_DELETE_STATUS\fR
.RS 4
\fIparams\fR
returns
\fBGL_TRUE\fR
if
\fIshader\fR
is currently flagged for deletion, and
\fBGL_FALSE\fR
otherwise\&.
.RE
.PP
\fBGL_COMPILE_STATUS\fR
.RS 4
\fIparams\fR
returns
\fBGL_TRUE\fR
if the last compile operation on
\fIshader\fR
was successful, and
\fBGL_FALSE\fR
otherwise\&.
.RE
.PP
\fBGL_INFO_LOG_LENGTH\fR
.RS 4
\fIparams\fR
returns the number of characters in the information log for
\fIshader\fR
including the null termination character (i\&.e\&., the size of the character buffer required to store the information log)\&. If
\fIshader\fR
has no information log, a value of 0 is returned\&.
.RE
.PP
\fBGL_SHADER_SOURCE_LENGTH\fR
.RS 4
\fIparams\fR
returns the length of the concatenation of the source strings that make up the shader source for the
\fIshader\fR, including the null termination character\&. (i\&.e\&., the size of the character buffer required to store the shader source)\&. If no source code exists, 0 is returned\&.
.RE
.SH "NOTES"
.PP
If an error is generated, no change is made to the contents of
\fIparams\fR\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_VALUE\fR
is generated if
\fIshader\fR
is not a value generated by OpenGL\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated if
\fIshader\fR
does not refer to a shader object\&.
.PP
\fBGL_INVALID_ENUM\fR
is generated if
\fIpname\fR
is not an accepted value\&.
