nlist - get entries from name list SYNOPSIS
#include <nlist.h> nlist(filename, nl) char *filename; struct nlist nl[]; DESCRIPTION
Nlist examines the name list in the given executable output file and selectively extracts a list of values. The name list consists of an array of structures containing names, types and values. The list is terminated with a null name. Each name is looked up in the name list of the file. If the name is found, the type and value of the name are inserted in the next two fields. If the name is not found, both entries are set to 0. See a.out(5) for the structure declaration. This subroutine is useful for examining the system name list kept in the file /vmunix. In this way programs can obtain system addresses that are up to date. SEE ALSO
If the file cannot be found or if it is not a valid namelist -1 is returned; otherwise, the number of unfound namelist entries is returned. The type entry is set to 0 if the symbol is not found. 4th Berkeley Distribution May 15, 1985 NLIST(3)

nlist - get entries from symbol table SYNOPSIS
/usr/ucb/cc [ flag ... ] file ... #include <nlist.h> int nlist(filename, nl); char *filename; struct nlist *nl; DESCRIPTION
nlist() examines the symbol table from the executable image 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 pointed to by nl consists of an array of structures contain- ing names, types and values. The n_name field of each such structure is taken to be a pointer to a character string representing 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 executable image's 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 zero. RETURN VALUES
Upon normal completion, nlist() returns the number of symbols that were not located in the symbol table. If an error occurs, nlist() returns -1 and sets all of the n_type fields in members of the array pointed to by nl to zero. SEE ALSO
nlist(3ELF), a.out(4) NOTES
Use of these interfaces should be restricted to only applications written on BSD platforms. Use of these interfaces with any of the system libraries or in multi-thread applications is unsupported. Only the n_value field is compatibly set. Other fields in the nlist structure are filled with the ELF (Executable and Linking Format) values (see nlist(3ELF) and a.out(4)).
