I have the following code:
static void AprsMakeTimeHms(uint8_t* buffer, const uint32_t timestamp)
{
struct tm* timeStruct;// Extract timestamp
timeStruct = gmtime((long*)×tamp);// Check if we got a valid time back
if (timeStruct == NULL)
{
printf(“Null ts\r\n”);
sprintf((char*)buffer, “000000h”);
return;
}// Format buffer
sprintf((char*)buffer, “%2d%2d%2dh”, timeStruct->tm_hour, timeStruct->tm_min, timeStruct->tm_sec);
}It seems, however, that the struct pointer ends up being assigned NULL. I could swear this was working at some point. Any ideas?
Hi,
Sorry, this doesn’t look like a VisualGDB-related issue, so we are not able to provide much help with this. The best advice we could give would be to look through the source code of your C library or asking on StackOverflow.
Hi,
Thanks for the update and sorry for the confusion. The original code looked like a Linux application, where the C library is completely outside VisualGDB’s control. For embedded projects there are indeed several versions of the syscall implementations for different scenarios (e.g. with/without semihosting). VisualGDB should also be able to automatically download symbols and sources for those libraries and let you step into the syscalls, helping quickly understand which version is being used.
