General Discussion / [nvapi] help with compiling.

« on: November 10, 2011, 12:33:35 PM »

Hello I don't really know what I'm doing... ok I do, I'm trying to compile an example app in nvapi docs and here's what I get:

Code: [Select]

W:\NVAPI\R285-developer>gcc test.c -o test.exe
In file included from test.c:2:0:
NvApiDriverSettings.h:837:19: error: expected ':', ',', ';', '}' or '__attribute
__' before '*' token
NvApiDriverSettings.h:845:19: error: expected ':', ',', ';', '}' or '__attribute
__' before '*' token

Code: [Select]

#include "nvapi.h"
#include "NvApiDriverSettings.h"
#include <stdlib.h>
#include <stdio.h>
/*
This function is used to print to the command line a text message     describing the nvapi error and quits
*/
void PrintError(NvAPI_Status status)
{
NvAPI_ShortString szDesc = {0};
NvAPI_GetErrorMessage(status, szDesc);
printf(" NVAPI error: %s\n", szDesc);
exit(-1);
}
int main(int argc, char **argv)
{
NvAPI_Status status;

// (0) Initialize NVAPI. This must be done first of all
status = NvAPI_Initialize();
if (status != NVAPI_OK)         PrintError(status);
// (1) Create the session handle to access driver settings
NvDRSSessionHandle hSession = 0;
status = NvAPI_DRS_CreateSession(&hSession);
if (status != NVAPI_OK)         PrintError(status);
// (2) load all the system settings into the session
status = NvAPI_DRS_LoadSettings(hSession);
if (status != NVAPI_OK)         PrintError(status);
// (3) Obtain the Base profile. Any setting needs to be inside
// a profile, putting a setting on the Base Profile enforces it
// for all the processes on the system
NvDRSProfileHandle hProfile = 0;
status = NvAPI_DRS_GetBaseProfile(hSession, &hProfile);
if (status != NVAPI_OK)         PrintError(status);
// (4) Specify that we want the VSYNC disabled setting
// first we fill the NVDRS_SETTING struct, then we call the function
NVDRS_SETTING drsSetting = {0};
drsSetting.version = NVDRS_SETTING_VER;
drsSetting.settingId = VSYNCMODE_ID;
drsSetting.settingType = NVDRS_DWORD_TYPE;
drsSetting.u32CurrentValue = VSYNCMODE_FORCEOFF;
status = NvAPI_DRS_SetSetting(hSession, hProfile, &drsSetting);
if (status != NVAPI_OK)         PrintError(status);
// (5) Now we apply (or save) our changes to the system
status = NvAPI_DRS_SaveSettings(hSession);
if (status != NVAPI_OK)         PrintError(status);
// (6) We clean up. This is analogous to doing a free()
NvAPI_DRS_DestroySession(hSession);
hSession = 0;
return 0;
}
