.SH "NAME"
glCreateShader \- Creates a shader object
.SH "C SPECIFICATION"
.HP \w'GLuint\ glCreateShader('u
.BI "GLuint glCreateShader(GLenum\ " "shaderType" ");"
.SH "PARAMETERS"
.PP
\fIshaderType\fR
.RS 4
Specifies the type of shader to be created\&. Must be one of
\fBGL_COMPUTE_SHADER\fR,
\fBGL_VERTEX_SHADER\fR,
\fBGL_TESS_CONTROL_SHADER\fR,
\fBGL_TESS_EVALUATION_SHADER\fR,
\fBGL_GEOMETRY_SHADER\fR, or
\fBGL_FRAGMENT_SHADER\fR\&.
.RE
.SH "DESCRIPTION"
.PP
\fBglCreateShader\fR
creates an empty shader object and returns a non\-zero value by which it can be referenced\&. A shader object is used to maintain the source code strings that define a shader\&.
\fIshaderType\fR
indicates the type of shader to be created\&. Five types of shader are supported\&. A shader of type
\fBGL_COMPUTE_SHADER\fR
is a shader that is intended to run on the programmable compute processor\&. A shader of type
\fBGL_VERTEX_SHADER\fR
is a shader that is intended to run on the programmable vertex processor\&. A shader of type
\fBGL_TESS_CONTROL_SHADER\fR
is a shader that is intended to run on the programmable tessellation processor in the control stage\&. A shader of type
\fBGL_TESS_EVALUATION_SHADER\fR
is a shader that is intended to run on the programmable tessellation processor in the evaluation stage\&. A shader of type
\fBGL_GEOMETRY_SHADER\fR
is a shader that is intended to run on the programmable geometry processor\&. A shader of type
\fBGL_FRAGMENT_SHADER\fR
is a shader that is intended to run on the programmable fragment processor\&.
.PP
When created, a shader object\*(Aqs
\fBGL_SHADER_TYPE\fR
parameter is set to either
\fBGL_COMPUTE_SHADER\fR,
\fBGL_VERTEX_SHADER\fR,
\fBGL_TESS_CONTROL_SHADER\fR,
\fBGL_TESS_EVALUATION_SHADER\fR,
\fBGL_GEOMETRY_SHADER\fR
or
\fBGL_FRAGMENT_SHADER\fR, depending on the value of
\fIshaderType\fR\&.
.SH "NOTES"
.PP
Like buffer and texture objects, the name space for shader objects may be shared across a set of contexts, as long as the server sides of the contexts share the same address space\&. If the name space is shared across contexts, any attached objects and the data associated with those attached objects are shared as well\&.
.PP
Applications are responsible for providing the synchronization across API calls when objects are accessed from different execution threads\&.
.PP
\fBGL_COMPUTE_SHADER\fR
is available only if the GL version is 4\&.3 or higher\&.
.SH "ERRORS"
.PP
This function returns 0 if an error occurs creating the shader object\&.
.PP
\fBGL_INVALID_ENUM\fR
is generated if
\fIshaderType\fR
is not an accepted value\&.
.SH "ASSOCIATED GETS"
.PP
\fBglGetShader\fR()
with a valid shader object and the parameter to be queried
.PP
\fBglGetShaderInfoLog\fR()
with a valid shader object
.PP
\fBglGetShaderSource\fR()
with a valid shader object
