glCreateShaderProgramv — create a stand-alone program from an array of null-terminated source code strings

C Specification

GLuint glCreateShaderProgramv(GLenum type, GLsizei count, const char **strings);

Parameters

type

Specifies the type of shader to create.

count

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 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.
