Retrieves the widths, in logical units, of consecutive glyph indices in a specified range from the current TrueType font.
Specifies the first glyph index in the group of consecutive glyph indices from the current font. This parameter is only used if the pgi parameter is NULL.
Specifies the number of glyph indices.
A pointer to an array containing glyph indices. If the value is NULL, the giFirst parameter is used instead. The cgi parameter specifies the number of glyph indices in this array.
Pointer to an array of ABC structures receiving the character widths. This array must contain at least as many ABC structures as there are glyph indices specified by the cgi parameter.
Nonzero if the function is successful; otherwise 0.
This member function emulates the functionality of the function GetCharABCWidthsI, as described in the Windows SDK.
