"man memset" shows the following synopsis for the memset function: #include <string.h> void *memset(const void *DST, int C, size_t LENGTH); The "const" on the first parameter is incorrect. The correct prototype according to the C standard (both C90 and C99) is: void *memset(void *s, int c, size_t n); (The differing parameter names are ok.) The problem is only in the documentation; the actual declaration doesn't have the const: % echo '#include <string.h>' | gcc -E - | grep memset void * __attribute__((__cdecl__)) memset (void *, int, size_t); This was found by a poster on comp.lang.c calling himself "Noob <root AT 127 DOT 0 DOT 0 DOT 1>". -- Keith Thompson (The_Other_Keith) kst AT mib DOT org <http://www.ghoti.net/~kst> Nokia "We must do something.
