#define ASSERT (  expr   )

Debugging ASSERT macro If CONFIG_DEBUG is set, the ASSERT() macro evaluates expr and if it is false raises kernel panic. Parameters: expr  Expression which is expected to be true.

__address get_symbol_addr (  const char *  name  )

Return address that corresponds to the entry Search symbol table, and if there is one match, return it Parameters: name  Name of the symbol Returns: 0 - Not found, -1 - Duplicate symbol, other - address of symbol Definition at line 111 of file symtab.c.

static char* symtab_search_one (  const char *  name, int *  startpos )  [static]

Find symbols that match the parameter forward and print them. Parameters: name  - search string startpos  - starting position, changes to found position Returns: Pointer to the part of string that should be completed or NULL Definition at line 72 of file symtab.c.
