fcft_precompose(3)                   fcft                   fcft_precompose(3)

NAME
       fcft_precompose - pre-compose two wide characters into one

SYNOPSIS
       #include <fcft/fcft.h>

       bool fcft_precompose(
           const struct fcft_font *font, uint32_t base, uint32_t comb, bool
           *base_is_from_primary, bool *comb_is_from_primary, bool
           *composed_is_from_primary);

DESCRIPTION
       fcft_precompose() composes the base and comb wide characters into a
       single wide character. For example, L'a' + L'\u0301' can be combined to
       L'a'.

       If *_is_from_primary are non-NULL, they will be true if the
       corresponding wide character exists in the primary font. If false, it
       does not exist in the primary font and fcft_codepoint_rasterize() will
       pick the glyph from one of the fallback fonts.

RETURN VALUE
       On success, fcft_precompose() returns a composed wide character. On
       error, (uint32_t)-1 is returned.
