函数名称：kdb_symbol_print - Standard method for printing a symbol name and offset

函数原型：void kdb_symbol_print(unsigned long addr, const kdb_symtab_t *symtab_p, unsigned int punc)

返回类型：void

参数：

类型参数名称
unsigned longaddr
const kdb_symtab_t *symtab_p
unsigned intpunc
262  如果symtab_p则
263  symtab_p2等于symtab_p
264  否则
265  symtab_p2等于symtab
266  kdbnearsym - Return the name of the symbol with the nearest address* less than 'addr'
268  如果非Full symbol name, including* any version 或punc按位与Print the value of the address 的值则返回
270  如果punc按位与Space before string 则kdb_printf(" ")
272  如果punc按位与Print the value of the address 则kdb_printf(kdb_machreg_fmt0, addr)
274  如果Full symbol name, including* any version 则
275  如果punc按位与Print the value of the address 则kdb_printf(" ")
277  如果punc按位与Parenthesis around string 则kdb_printf("(")
279  如果字符串比较则kdb_printf("[%s]", Module containing symbol or* "kernel" )
281  kdb_printf("%s", Full symbol name, including* any version )
282  如果addr不等于sym_start则kdb_printf("+0x%lx", addr - sym_start)
284  如果punc按位与Print the size of the symbol 则kdb_printf("/0x%lx", sym_end - sym_start)
287  如果punc按位与Parenthesis around string 则kdb_printf(")")
290  如果punc按位与Space after string 则kdb_printf(" ")
292  如果punc按位与Newline after string 则kdb_printf("\n")
