Standard C Library (libc, -lc)
#include <nlist.h>
int
nlist
(const
char *filename, struct
nlist *nl);
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
.
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.
A nlist
() function appeared in
Version 6 AT&T UNIX.
