NAME fglIsTexture - determine if a name corresponds to a texture FORTRAN SPECIFICATION LOGICAL*1 fglIsTexture( INTEGER*4 texture ) PARAMETERS texture Specifies a value that may be the name of a texture. DESCRIPTION fglIsTexture returns GL_TRUE if texture is currently the name of a texture. If texture is zero, or is a non-zero value that is not currently the name of a texture, or if an error occurs, fglIsTexture returns GL_FALSE. NOTES fglIsTexture is available only if the GL version is 1.1 or greater. ERRORS GL_INVALID_OPERATION is generated if fglIsTexture is executed between the execution of fglBegin and the corresponding execution of fglEnd.
