Since the regress tool limits +** the output to a one line status:PASS or FAIL,all of the printf statements +** have been handled with an if (debug_mode) statement. +** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to +** recognize the return code from tha main program. +** 12-June-97 Revert to return code 0 and 1. +***********************************************************************/ + +/*********************************************************************** +** Includes +***********************************************************************/ +#include "prinit.h" +#include "prlink.h" +#include "prmem.h" +#include "prerror.h" + +#include "plstr.h" + +#include <stdio.h> +#include <stdlib.h> + +typedef PRIntn (PR_CALLBACK *GetFcnType)(void); +typedef void (PR_CALLBACK *SetFcnType)(PRIntn); + +PRIntn failed_already=0; +PRIntn debug_mode; + +int main(int argc, char** argv) +{ + PRLibrary *lib, *lib2; /* two handles to the same library */ + GetFcnType getFcn; + SetFcnType setFcn; + PRIntn value; + PRStatus status; + char *libName; + + if (argc >= 2 && PL_strcmp(argv[1], "-d") == 0) { + debug_mode = 1; + } + + PR_Init(PR_USER_THREAD, PR_PRIORITY_NORMAL, 0); + PR_STDIO_INIT(); + + /* + * Test 1: load the library, look up the symbols, call the functions, + * and check the results. + */ + + libName = PR_GetLibraryName("dll", "my"); + if (debug_mode) { + printf("Loading library %s\n", libName); + } + lib = PR_LoadLibrary(libName); + PR_FreeLibraryName(libName); + if (lib == NULL) { + PRInt32 textLength = PR_GetErrorTextLength(); + char *text = (char*)PR_MALLOC(textLength + 1); + text[0] = '\0'; + (void)PR_GetErrorText(text); + fprintf( + stderr, "PR_LoadLibrary failed (%d, %d, %s)\n", + PR_GetError(), PR_GetOSError(), text); + if (!debug_mode) { + failed_already=1; + } + } + getFcn = (GetFcnType) PR_FindSymbol(lib, "My_GetValue"); + setFcn = (SetFcnType) PR_FindFunctionSymbol(lib, "My_SetValue"); + (*setFcn)(888); + value = (*getFcn)(); + if (value != 888) { + fprintf(stderr, "Test 1 failed: set value to 888, but got %d\n", value); + if (!debug_mode) { + failed_already=1; + } + } + if (debug_mode) { + printf("Test 1 passed\n"); + } + + /* + * Test 2: get a second handle to the same library (this should increment + * the reference count), look up the symbols, call the functions, and + * check the results. + */ + + getFcn = (GetFcnType) PR_FindSymbolAndLibrary("My_GetValue", &lib2); + if (NULL == getFcn || lib != lib2) { + fprintf(stderr, "Test 2 failed: handles for the same library are not " + "equal: handle 1: %p, handle 2: %p\n", lib, lib2); + if (!debug_mode) { + failed_already=1; + } + } + setFcn = (SetFcnType) PR_FindSymbol(lib2, "My_SetValue"); + value = (*getFcn)(); + if (value != 888) { + fprintf(stderr, "Test 2 failed: value should be 888, but got %d\n", + value); + if (!debug_mode) { + failed_already=1; + } + } + (*setFcn)(777); + value = (*getFcn)(); + if (value != 777) { + fprintf(stderr, "Test 2 failed: set value to 777, but got %d\n", value); + if (!debug_mode) { + failed_already=1; + } + goto exit_now; + } + if (debug_mode) { + printf("Test 2 passed\n"); + } + + /* + * Test 3: unload the library.
