HSM functions reference
A number of libraries are required to use the functionality provided by the Thales FM SDK. This chapter describes the function sets provided by these libraries.
As well as the functions described in this section, the full set of PKCS#11 functions are also available to the FM. The PKCS#11 functions are described in the Cprov Programmer Manual, and the PKCS#11 standard. The library libfmcprov.a provides the PKCS#11 functions.
Summary
Subset of ISO C99 standard library
The FM SDK supports a subset of the ISO C 99 standard library, as defined by ISO/IEC 9899:1999. In general, floating point math, multibyte character, localization and I/O APIs are not supported; printf and vprintf are exceptions and are redirected to the logging channel.
In addition to the standard library, C99 language features not present in ANSI C (C89/90) can be used.
The following functions are provided by libfmcrt.a:
assert.h
assert
ctype.h
isalnum, isalpha, isblank, iscntrl, isdigit, isgraph, islower, isprint, ispunct, isspace, isupper, isxdigit, tolower, toupper
stdio.h
printf, sprintf, sscanf, vprintf, vsprintf, snprintf, vsnprintf, vsscanf
stdarg.h
va_arg(), va_start(), va_end(), va_copy()
stdlib.h
abs, atoi, atol, atoll, bsearch, calloc, div, free, labs, llabs, ldiv, lldiv, malloc, qsort, rand, realloc, srand, strtol, strtoll, strtoul, strtoull
string.h
memchr, memcmp, memcpy, memmove, memset, strcat, strchr, strcmp, strcpy, strcspn, strlen, strncat, strncmp, strncpy, strpbrk, strrchr, strspn, strstr, strerror, strtok
time.h
asctime, clock, ctime, gmtime, mktime, strftime, time, difftime
Extensions to the standard C API
The FMS SDK also supports the following common, but non-ISO library functions in their GNU form.
Note
These may not be available in emulation mode. See Supported C APIs.
ctype.h
isascii, toascii
string.h
strdup, strsep
Unsupported standard C APIs
The following standard headers and their contained APIs are not supported by the FM SDK:
complex.h, fenv.h, float.h, locale.h, math.h, signal.h, tgmath.h, wchar.h, and wctype.h
