Function Documentation

struct vfont* vfont_get (   )

void vfont_free (   )

struct vfont* vfont_get (  char *  font  )

V F O N T _ G E T Fetch the named font, and return a struct vfont pointer. First the filename provided is used, then the BRL-CAD font directory is searched (for places where "system" directories are considered sacred), and then finally the ordinary font directory is searched. The font files are treated as pure byte streams, and are expected to be in VAX order. VFONT_NULL is returned on error. On ordinary errors, the function is silent. On extraordinary errors, a remark is placed on stderr. Definition at line 79 of file vfont.c.
