| Variables | Description |
|---|---|
| type |
Specifies the type of shader to create.

Specifies the number of source code strings in the array
strings
.
|
| strings |
Specifies the address of an array of pointers to source code strings from which to create the program object.

Description
glCreateShaderProgram
creates a program object containing compiled and linked
shaders for a single stage specified by
type
.
strings
refers to an array of
count
strings from which to create the shader executables.
glCreateShaderProgram
is equivalent (assuming no errors are generated) to:
const GLuint shader = glCreateShader(type);
if (shader) {
glShaderSource(shader, count, strings, NULL);
glCompileShader(shader);
const GLuint program = glCreateProgram();
if (program) {
GLint compiled = GL_FALSE;
glGetShaderiv(shader, GL_COMPILE_STATUS, &compiled);
glProgramParameteri(program, GL_PROGRAM_SEPARABLE, GL_TRUE);
if (compiled) {
glAttachShader(program, shader);
glLinkProgram(program);
glDetachShader(program, shader);
}
/* append-shader-info-log-to-program-info-log */
}
glDeleteShader(shader);
return program;
} else {
return 0;
}
The program object created by
glCreateShaderProgram
has its
GL_PROGRAM_SEPARABLE
status set to
GL_TRUE
.
Errors
GL_INVALID_ENUM
is generated if
type
is not
an accepted shader type.
GL_INVALID_VALUE
is generated if
count
is
negative.
Other errors are generated if the supplied shader code fails to compile
and link, as described for the commands in the pseudocode sequence above,
but all such errors are generated without any side effects of executing those
commands.
