NAME
kvm_nlist - get entries from kernel symbol table SYNOPSIS
cc [ flag... ] file... -lkvm [ library...] #include <kvm.h> #include <nlist.h> int kvm_nlist(kvm_t *kd, struct nlist *nl); DESCRIPTION
The kvm_nlist() function examines the symbol table from the kernel image identified by kd (see kvm_open(3KVM)) and selectively extracts a list of values and puts them in the array of nlist structures pointed to by nl. The name list pointed to by nl consists of an array of structures containing names, types and values. The n_name field of each such structure is taken to be a pointer to a character string rep- resenting a symbol name. The list is terminated by an entry with a null pointer (or a pointer to a null string) in the n_name field. For each entry in nl, if the named symbol is present in the kernel symbol table, its value and type are placed in the n_value and n_type fields. If a symbol cannot be located, the corresponding n_type field of nl is set to 0. RETURN VALUES
The kvm_nlist() functions returns the value of nlist(3UCB) or nlist(3ELF), depending on the library used. ATTRIBUTES

NAME
nlist - get entries from name list SYNOPSIS
cc [ flag... ] file ... -lelf [ library ... ] #include <nlist.h> int nlist(const char *filename, struct nlist *nl); DESCRIPTION
nlist() examines the name list in the executable file whose name is pointed to by filename, and selectively extracts a list of values and puts them in the array of nlist() structures pointed to by nl. The name list nl consists of an array of structures containing names of variables, types, and values. The list is terminated with a null name, that is, a null string is in the name position of the structure. Each variable name is looked up in the name list of the file. If the name is found, the type, value, storage class, and section number of the name are inserted in the other fields. The type field may be set to 0 if the file was not compiled with the -g option to cc(1B). nlist() will always return the information for an external symbol of a given name if the name exists in the file. If an external symbol does not exist, and there is more than one symbol with the specified name in the file (such as static symbols defined in separate files), the values returned will be for the last occurrence of that name in the file. If the name is not found, all fields in the structure except n_name are set to 0. This function is useful for examining the system name list kept in the file /dev/ksyms. In this way programs can obtain system addresses that are up to date. RETURN VALUES
All value entries are set to 0 if the file cannot be read or if it does not contain a valid name list. nlist() returns 0 on success, -1 on error. ATTRIBUTES
