.SH "NAME"
glCreateProgram \- Creates a program object
.SH "C SPECIFICATION"
.HP \w'GLuint\ glCreateProgram('u
.BI "GLuint glCreateProgram(" "void" ");"
.SH "DESCRIPTION"
.PP
\fBglCreateProgram\fR
creates an empty program object and returns a non\-zero value by which it can be referenced\&. A program object is an object to which shader objects can be attached\&. This provides a mechanism to specify the shader objects that will be linked to create a program\&. It also provides a means for checking the compatibility of the shaders that will be used to create a program (for instance, checking the compatibility between a vertex shader and a fragment shader)\&. When no longer needed as part of a program object, shader objects can be detached\&.
.PP
One or more executables are created in a program object by successfully attaching shader objects to it with
\fBglAttachShader\fR(), successfully compiling the shader objects with
\fBglCompileShader\fR(), and successfully linking the program object with
\fBglLinkProgram\fR()\&. These executables are made part of current state when
\fBglUseProgram\fR()
is called\&. Program objects can be deleted by calling
\fBglDeleteProgram\fR()\&. The memory associated with the program object will be deleted when it is no longer part of current rendering state for any context\&.
.SH "NOTES"
.PP
Like buffer and texture objects, the name space for program 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\&.
.SH "ERRORS"
.PP
This function returns 0 if an error occurs creating the program object\&.
