NLIST(3)						   BSD Library Functions Manual 						  NLIST(3)

NAME

     nlist -- retrieve symbol table name list from an executable file

LIBRARY

     Utility functions from BSD systems (libbsd, -lbsd)

SYNOPSIS

     #include <bsd/nlist.h>

     int
     nlist(const char *filename, struct nlist *nl);

DESCRIPTION

     The nlist() function retrieves name list entries from the symbol table of an executable file (see a.out(5)).  The argument nl is set to ref-
     erence the beginning of the list.	The list is preened of binary and invalid data; if an entry in the name list is valid, the n_type and
     n_value for the entry are copied into the list referenced by nl.  No other data is copied.  The last entry in the list is always NULL.

RETURN VALUES

     The number of invalid entries is returned if successful; otherwise, if the file filename does not exist or is not executable, the returned
     value is -1.

SEE ALSO

     a.out(5)

HISTORY

     A nlist() function appeared in Version 6 AT&T UNIX.

NAME

     kvm_nlist -- retrieve symbol table names from a kernel image

LIBRARY

     Kernel Data Access Library (libkvm, -lkvm)

SYNOPSIS

     #include <kvm.h>
     #include <nlist.h>

     int
     kvm_nlist(kvm_t *kd, struct nlist *nl);

DESCRIPTION

     The kvm_nlist() function retrieves the symbol table entries indicated by the name list argument nl.  This argument points to an array of
     nlist structures, terminated by an entry whose n_name field is NULL (see nlist(3)).  Each symbol is looked up using the n_name field, and if
     found, the corresponding n_type and n_value fields are filled in.	These fields are set to 0 if the symbol is not found.

     The kldsym(2) system call is used to locate the symbol.  This is a less than perfect emulation of the nlist values but has the advantage of
     being aware of kernel modules and is reasonably fast.

RETURN VALUES

     The kvm_nlist() function returns the number of invalid entries found.  If the kernel symbol table was unreadable, -1 is returned.
