DESCRIPTION
The kldsym system call returns the address of the symbol specified in data in the module specified by fileid. If fileid is 0, all loaded modules are searched. Currently, the only command implemented is KLDSYM_LOOKUP. The data argument is of the following structure:
struct kld_sym_lookup {
int version; /* sizeof(struct kld_sym_lookup) */
char *symname; /* Symbol name we are looking up */
u_long symvalue;
size_t symsize;
};
The version member is to be set by the code calling kldsym to sizeof "struct kld_sym_lookup". The next two members, version and symname, are specified by the user. The last two, symvalue and symsize, are filled in by kldsym and contain the address associated with symname and the size of the data it points to, respectively.
RETURN VALUES
.Rv -std kldsym
ERRORS
The kldsym system call will fail if:
