    .SH "NAME" glIsProgram - Determines if a name corresponds to a program object
    .SH "C SPECIFICATION"

        .SH "DESCRIPTION"
        .PP glIsProgram returns GL_TRUE if program is the name of a program object previously created with glCreateProgram() and not yet deleted with glDeleteProgram(). If program is zero or a non-zero value that is not the name of a program object, or if an error occurs, glIsProgram returns GL_FALSE.

        .SH "NOTES"
        .PP No error is generated if program is not a valid program object name.
        .PP A program object marked for deletion with glDeleteProgram() but still in use as part of current rendering state is still considered a program object and glIsProgram will return GL_TRUE.
