- _d_i_s_p_l_a_y Specifies the connection to the X server.
-
- _c_o_l_o_r_m_a_p Specifies the colormap.
-
- _c_o_l_o_r___e_x_a_c_t___r_e_t_u_r_n
- Returns the color specification parsed from the
- color string or parsed from the corresponding
- string found in a color-name database.
-
- _c_o_l_o_r___i_n___o_u_t
- Specifies the color to allocate and returns the
- pixel and color that is actually used in the
- colormap.
-
- _c_o_l_o_r___s_c_r_e_e_n___r_e_t_u_r_n
- Returns the pixel value of the color cell and
- color specification that actually is stored for
- that cell.
-
- _c_o_l_o_r___s_t_r_i_n_g
- Specifies the color string whose color defini-
- tion structure is to be returned.
-
- _r_e_s_u_l_t___f_o_r_m_a_t
- Specifies the color format for the returned
- color specification.

- The _X_c_m_s_A_l_l_o_c_C_o_l_o_r function is similar to _X_A_l_l_o_c_C_o_l_o_r
- except the color can be specified in any format. The _X_c_m_-
- _s_A_l_l_o_c_C_o_l_o_r function ultimately calls _X_A_l_l_o_c_C_o_l_o_r to allo-
- cate a read-only color cell (colormap entry) with the

- specified color. _X_c_m_s_A_l_l_o_c_C_o_l_o_r first converts the color
- specified to an RGB value and then passes this to
- _X_A_l_l_o_c_C_o_l_o_r. _X_c_m_s_A_l_l_o_c_C_o_l_o_r returns the pixel value of
- the color cell and the color specification actually allo-
- cated. This returned color specification is the result of
- converting the RGB value returned by _X_A_l_l_o_c_C_o_l_o_r into the
- format specified with the result_format argument. If
- there is no interest in a returned color specification,
- unnecessary computation can be bypassed if result_format
- is set to _X_c_m_s_R_G_B_F_o_r_m_a_t. The corresponding colormap cell
- is read-only. If this routine returns _X_c_m_s_F_a_i_l_u_r_e, the
- color_in_out color specification is left unchanged.
-
- _X_c_m_s_A_l_l_o_c_C_o_l_o_r can generate a _B_a_d_C_o_l_o_r errors.
-
- The _X_c_m_s_A_l_l_o_c_N_a_m_e_d_C_o_l_o_r function is similar to _X_A_l_l_o_c_-
- _N_a_m_e_d_C_o_l_o_r except that the color returned can be in any
- format specified. This function ultimately calls _X_A_l_l_o_c_-
- _C_o_l_o_r to allocate a read-only color cell with the color
- specified by a color string. The color string is parsed
- into an _X_c_m_s_C_o_l_o_r structure (see _X_c_m_s_L_o_o_k_u_p_C_o_l_o_r), con-
- verted to an RGB value, and finally passed to _X_A_l_l_o_c_C_o_l_o_r.
- If the color name is not in the Host Portable Character
- Encoding, the result is implementation-dependent. Use of
- uppercase or lowercase does not matter.
-
- This function returns both the color specification as a
- result of parsing (exact specification) and the actual
- color specification stored (screen specification). This
- screen specification is the result of converting the RGB
- value returned by _X_A_l_l_o_c_C_o_l_o_r into the format specified in
- result_format. If there is no interest in a returned
- color specification, unnecessary computation can be
- bypassed if result_format is set to _X_c_m_s_R_G_B_F_o_r_m_a_t. If
- color_screen_return and color_exact_return point to the
- same structure, the pixel field will be set correctly, but
- the color values are undefined.

-
- _X_c_m_s_A_l_l_o_c_N_a_m_e_d_C_o_l_o_r can generate a _B_a_d_C_o_l_o_r errors.
