.SH "NAME"
glAttachShader \- Attaches a shader object to a program object
.SH "C SPECIFICATION"
.HP \w'void\ glAttachShader('u
.BI "void glAttachShader(GLuint\ " "program" ", GLuint\ " "shader" ");"
.SH "PARAMETERS"
.PP
\fIprogram\fR
.RS 4
Specifies the program object to which a shader object will be attached\&.
.RE
.PP
\fIshader\fR
.RS 4
Specifies the shader object that is to be attached\&.
.RE
.SH "DESCRIPTION"
.PP
In order to create a complete shader program, there must be a way to specify the list of things that will be linked together\&. Program objects provide this mechanism\&. Shaders that are to be linked together in a program object must first be attached to that program object\&.
\fBglAttachShader\fR
attaches the shader object specified by
\fIshader\fR
to the program object specified by
\fIprogram\fR\&. This indicates that
\fIshader\fR
will be included in link operations that will be performed on
\fIprogram\fR\&.
.PP
All operations that can be performed on a shader object are valid whether or not the shader object is attached to a program object\&. It is permissible to attach a shader object to a program object before source code has been loaded into the shader object or before the shader object has been compiled\&. It is permissible to attach multiple shader objects of the same type because each may contain a portion of the complete shader\&. It is also permissible to attach a shader object to more than one program object\&. If a shader object is deleted while it is attached to a program object, it will be flagged for deletion, and deletion will not occur until
\fBglDetachShader\fR()
is called to detach it from all program objects to which it is attached\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_VALUE\fR
is generated if either
\fIprogram\fR
or
\fIshader\fR
is not a value generated by OpenGL\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated if
\fIprogram\fR
is not a program object\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated if
\fIshader\fR
is not a shader object\&.
.PP
\fBGL_INVALID_OPERATION\fR
is generated if
\fIshader\fR
is already attached to
\fIprogram\fR\&.
.SH "ASSOCIATED GETS"
