This is NSS with a Cmake Buildsyste
To compile a static NSS library for Windows we've used the
Chromium-NSS fork and added a Cmake buildsystem to compile
it statically for Windows. See README.chromium for chromium
changes and README.trustbridge for our modifications.

| 87 ** FUNCTION: PR_sscanf | |
| 88 ** DESCRIPTION: | |
| 89 ** PR_sscanf() scans the input character string, performs data | |
| 90 ** conversions, and stores the converted values in the data objects | |
| 91 ** pointed to by its arguments according to the format control | |
| 92 ** string. | |
| 93 ** | |
| 94 ** PR_sscanf() behaves the same way as the sscanf() function in the | |
| 95 ** Standard C Library (stdio.h), with the following exceptions: | |
| 96 ** - PR_sscanf() handles the NSPR integer and floating point types, | |
| 97 ** such as PRInt16, PRInt32, PRInt64, and PRFloat64, whereas | |
| 98 ** sscanf() handles the standard C types like short, int, long, | |
| 99 ** and double. | |
| 100 ** - PR_sscanf() has no multibyte character support, while sscanf() | |
| 101 ** does. | |
| 102 ** INPUTS: | |
| 103 ** const char *buf | |
| 104 ** a character string holding the input to scan | |
| 105 ** const char *fmt | |
| 106 ** the format control string for the conversions | |
| 107 ** ... | |
| 108 ** variable number of arguments, each of them is a pointer to | |
| 109 ** a data object in which the converted value will be stored | |
| 110 ** OUTPUTS: none | |
| 111 ** RETURNS: PRInt32 | |
| 112 ** The number of values converted and stored. | |
| 113 ** RESTRICTIONS: | |
| 114 ** Multibyte characters in 'buf' or 'fmt' are not allowed. | |
