Types¶

struct SDTProvider_t¶

Represents a USDT Provider. A USDT Provider is basically a namespace for USDT probes. Shouldn’t be created manually, use providerInit() instead.

char *name¶: Provider’s name

SDTProbeList_t *probes¶: Linked-list of registered probes

SDTError_t errno¶: Error code of the last error for this provider

char *error¶: Error string of the last error for this provider

struct SDTProbe_t¶

Represents a USDT Probe. A probe is basically a software breakpoint. Shouldn’t be created manually, use providerAddProbe() instead.

char *name¶: Probe’s name

ArgType_t argFmt[MAX_ARGUMENTS]: Array holding all arguments accepted by this probe.

struct SDTProvider *provider¶: Pointer to this probe’s provider

int argCount¶: Number of accepted arguments

enum SDTArgTypes_t¶

Represents all accepted arguments defined by Systeptap’s SDT probes.

noarg¶: No argument

uint8¶: 8 bits unsigned int

int8¶: 8 bits signed int

uint16¶: 16 bits unsigned int

int16¶: 16 bits signed int

uint32¶: 32 bits unsigned int

int32¶: 32 bits signed int

uint64¶: 64 bits unsigned int

int64¶: 64 bits signed int

enum SDTError_t¶

Represents all errors thrown by libstapsdt.

noError¶: This error code means that no error occured so far

elfCreationError¶: This error code means that we were unable to create an Elf file to store our probes

tmpCreationError¶: This error code means that we were unable to open a temporary file at /tmp/. A common mistake here is having a / in the provider name, which will be interpreted by the operating system as a folder.

sharedLibraryOpenError¶: This error code means that we were unable to open the shared library that we just created

symbolLoadingError¶: This error code means that the we were unable to load a symbol from the shared library we just created

sharedLibraryCloseError¶: This error code means that we were unable to close the shared library for this provider

struct SDTProbeList_t¶

Represents a linked-list of SDTProbe_t. Shouldn’t be handled manually, use providerAddProbe() instead.

SDTProbe_t probe¶
