[SLUG] ask include file(redefinition)

[henry]

Dear List :   I got one driver  . I cant make it for such an error ------"redefinition of ssize_t"   one definition(as follows) is from /usr/src/linux/include/linux/types.h #ifndef _SSIZE_T #define _SSIZE_T typedef __kernel_ssize_t ssize_t; #endif   another definition(as follows) is from /usr/include/unistd.h #ifndef __ssize_t_defined typedef __ssize_t ssize_t; # define __ssize_t_defined #endif       But for some historical reason ,different definitions use the same term-  ssize_t .     Neglect the case of driver ,if one program  need both types.h & unistd.h. How could I do ? Could someone shed some light on it ?     Thanks in advance! Henry
