.SH "NAME"
glIsProgram \- Determines if a name corresponds to a program object
.SH "C SPECIFICATION"
.HP \w'GLboolean\ glIsProgram('u
.BI "GLboolean glIsProgram(GLuint\ " "program" ");"
.SH "PARAMETERS"
.PP
\fIprogram\fR
.RS 4
Specifies a potential program object\&.
.RE
.SH "DESCRIPTION"
.PP
\fBglIsProgram\fR
returns
\fBGL_TRUE\fR
if
\fIprogram\fR
is the name of a program object previously created with
\fBglCreateProgram\fR()
and not yet deleted with
\fBglDeleteProgram\fR()\&. If
\fIprogram\fR
is zero or a non\-zero value that is not the name of a program object, or if an error occurs,
\fBglIsProgram\fR
returns
\fBGL_FALSE\fR\&.
.SH "NOTES"
.PP
No error is generated if
\fIprogram\fR
is not a valid program object name\&.
.PP
A program object marked for deletion with
\fBglDeleteProgram\fR()
but still in use as part of current rendering state is still considered a program object and
\fBglIsProgram\fR
will return
\fBGL_TRUE\fR\&.
