If \f2texture\fP is zero, or is a non-zero value that is not currently the name of a texture, or if an error occurs, \%\f3glIsTexture\fP returns \%\f3GL_FALSE\fP. .SH NOTES \%\f3glIsTexture\fP is available only if the GL version is 1.1 or greater. .SH ERRORS \%\f3GL_INVALID_OPERATION\fP is generated if \%\f3glIsTexture\fP is executed between the execution of \%\f3glBegin\fP and the corresponding execution of \%\f3glEnd\fP. .SH SEE ALSO \%\f3glBindTexture\fP, \%\f3glCopyTexImage1D\fP, \%\f3glCopyTexImage2D\fP, \%\f3glDeleteTextures\fP, \%\f3glGenTextures\fP, \%\f3glGet\fP, \%\f3glGetTexParameter\fP, \%\f3glTexImage1D\fP, \%\f3glTexImage2D\fP, \%\f3glTexImage3D\fP, \%\f3glTexParameter\fP
