glCreateShader
3G
glCreateShader
create a shader object
C Specification
GLuint glCreateShader
GLenum shaderType
Parameters
shaderType
Specifies the type of shader to be created.
Must be either GL_VERTEX_SHADER
or GL_FRAGMENT_SHADER.
Description
glCreateShader 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. shaderType
indicates the type of shader to be created. Two types of shaders
are supported. A shader of type
GL_VERTEX_SHADER is a shader that is
intended to run on the programmable vertex processor. A shader of
type GL_FRAGMENT_SHADER is a shader that is
intended to run on the programmable fragment processor.
When created, a shader object's
GL_SHADER_TYPE parameter is set to either
GL_VERTEX_SHADER or
GL_FRAGMENT_SHADER, depending on the value
of shaderType.
Notes
Like 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.
Applications are responsible for providing the
synchronization across API calls when objects are accessed from
different execution threads.
Errors
This function returns 0 if an error occurs creating the
shader object.
GL_INVALID_ENUM is generated if
shaderType is not an accepted value.
