SYNTAX

Region XCreateRegion(void); int XSetRegion(Display *_d_i_s_p_l_a_y, GC _g_c, Region _r); int XDestroyRegion(Region _r);

ARGUMENTS

_d_i_s_p_l_a_y Specifies the connection to the X server.

DESCRIPTION

The _X_C_r_e_a_t_e_R_e_g_i_o_n function creates a new empty region.

The _X_S_e_t_R_e_g_i_o_n function sets the clip-mask in the GC to the specified region. The region is specified relative to the drawable's origin. The resulting GC clip origin is implementation-dependent. Once it is set in the GC, the region can be destroyed.

The _X_D_e_s_t_r_o_y_R_e_g_i_o_n function deallocates the storage associated with a specified region.
