Tss2_TctiLdr_GetInfo - Query TctiLdr library for the TSS2_TCTI_INFO structure associated with a TCTI library. #include <tss2/tss2_tctildr.h> "TSS2_RC Tss2_TctiLdr_GetInfo ("const char " "*name" ", TSS2_TCTI_INFO " "**info" ");" The Tss2_TctiLdr_GetInfo () function attempts to instantiate a TSS2_TCTI_INFO structure appropriate for the TCTI library associated with the provided name. The TSS2_TCTI_INFO* reference returned by this function must be freed by the Tss2_TctiLdr_FreeInfo () function. The name parameter is a C string. If this string is NULL then the library will select a default TCTI for the caller. This is the same TCTI library that will be used to initialize the context returned by Tss2_TctiLdr_Initialize when passed a NULL name. If non-NULL, the Tss2_TctiLdr_GetInfo () uses the same algorithm to map the string to the name of an installed TCTI library as the Tss2_TctiLdr_Initialize () function. The info parameter is a reference to a TSS2_TCTI_INFO*. The reference returned will be allocated by the function and must be freed by the caller. A successful call to this function will return TSS2_RC_SUCCESS. An unsuccessful call to this function will return a response code described below in section ERRORS. TSS2_TCTI_RC_MEMORY is returned if memory allocation fails TSS2_TCTI_RC_NOT_SUPPORTED is returned when the loader is unable to locate a TCTI library with the provided name TSS2_TCTI_RC_IO_ERROR is returned if a failure occurs in the underlying library loading mechanism TSS2_TCTI_RC_BAD_REFERENCE is returned if the info parameter is NULL Example code.
