glcIsContext(3G) OpenGL Character Renderer glcIsContext(3G)
NAME
glcIsContext - test whether a context ID is the current GLC context
C SPECIFICATION
GLboolean glcIsContext( GLint inContext )
PARAMETERS
inContext Specifies the context ID to be tested.
DESCRIPTION
glcIsContext checks whether inContext is the ID of one of the client's
GLC context and returns GLC_TRUE if and only if it is.
Each GLC context has a nonzero ID of type GLint. When a client is linked
with a GLC library, the library maintains a list of IDs that contains one
entry for each of the client's GLC contexts. The list is initially empty.
Each client thread has a private GLC context ID variable that always
contains either the value zero, indicating that the thread has no current
GLC context, or the ID of the thread's current GLC context. The initial
value is zero.
