NAME
 nlist — retrieve symbol table name list from an executable file
LIBRARY
 Standard C Library (libc, -lc)
SYNOPSIS
 #include <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 reference 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.
HISTORY
 A nlist() function appeared in Version 6 AT&T UNIX.
