Finds a symbol in one of the currently loaded libraries, and returns both the symbol and the library in which it was found.
Syntax
#include <prlink.h> void* PR_FindSymbolAndLibrary ( const char *name, PRLibrary **lib);
Parameters
The function has these parameters:
name- The textual representation of the symbol to locate.
lib- A reference to a location at which the runtime will store the library in which the symbol was discovered. This location must be pre-allocated by the caller.
Returns
If successful, returns a non-NULL pointer to the found symbol, and stores a pointer to the library in which it was found at the location pointed to by lib.
If the symbol could not be found, returns NULL.
Description
This function finds the specified symbol in one of the currently loaded libraries. It returns the address of the symbol. Upon return, the location pointed to by the parameter lib contains a pointer to the library that contains that symbol. The location must be pre-allocated by the caller.
The function returns NULL if no such function can be found. The order in which the known libraries are searched in not specified. This function is equivalent to calling first PR_LoadLibrary, then PR_FindSymbol.
The identity returned from this function must be the target of a PR_UnloadLibrary in order to return the runtime to its original state.
