To do that, define * __REG_WIDE_T to the type of wide characters (unfortunately, there * is no consensus that wchar_t is suitable) and __REG_WIDE_COMPILE and * __REG_WIDE_EXEC to the names to be used for the compile and execute * functions (suggestion: re_Xcomp and re_Xexec, where X is a letter * suggestive of the wide type, e.g. re_ucomp and re_uexec for Unicode). * For cranky old compilers, it may be necessary to do something like: * #define __REG_WIDE_COMPILE(a,b,c,d) re_Xcomp(a,b,c,d) * #define __REG_WIDE_EXEC(a,b,c,d,e,f,g) re_Xexec(a,b,c,d,e,f,g) * rather than just #defining the names as parameterless macros. * * For some specialized purposes, it may be desirable to suppress the * declarations of the "front end" functions, regcomp() and regexec(), * or of the char versions of the compile and execute functions. To * suppress the front-end functions, define __REG_NOFRONT. To suppress * the char versions, define __REG_NOCHAR. * * The right place to do those defines (and some others you may want, see * below) would be <sys/types.h>. If you don't have control of that file, * the right place to add your own defines to this file is marked below. * This is normally done automatically, by the makefile and regmkhdr, based * on the contents of regcustom.h. */ /* * voodoo for C++ */ #ifdef __cplusplus extern "C" { #endif /* * Add your own defines, if needed, here. */ /* * Location where a chunk of regcustom.h is automatically spliced into * this file (working from its prototype, regproto.h). */ /* --- begin --- */ /* ensure certain things don't sneak in from system headers */ #ifdef __REG_WIDE_T #undef __REG_WIDE_T #endif #ifdef __REG_WIDE_COMPILE #undef __REG_WIDE_COMPILE #endif #ifdef __REG_WIDE_EXEC #undef __REG_WIDE_EXEC #endif #ifdef __REG_REGOFF_T #undef __REG_REGOFF_T #endif #ifdef __REG_VOID_T #undef __REG_VOID_T #endif #ifdef __REG_CONST #undef __REG_CONST #endif #ifdef __REG_NOFRONT #undef __REG_NOFRONT #endif #ifdef __REG_NOCHAR #undef __REG_NOCHAR #endif /* interface types */ #define __REG_WIDE_T Tcl_UniChar #define __REG_REGOFF_T long /* not really right, but good enough... */ #define __REG_VOID_T VOID #define __REG_CONST CONST /* names and declarations */ #define __REG_WIDE_COMPILE TclReComp #define __REG_WIDE_EXEC TclReExec #define __REG_NOFRONT /* don't want regcomp() and regexec() */ #define __REG_NOCHAR /* or the char versions */ #define regfree TclReFree #define regerror TclReError /* --- end --- */ /* * interface types etc. */ /* * regoff_t has to be large enough to hold either off_t or ssize_t, * and must be signed;
