| 116 ** FUNCTION: PR_sscanf | |
| 117 ** DESCRIPTION: | |
| 118 ** PR_sscanf() scans the input character string, performs data | |
| 119 ** conversions, and stores the converted values in the data objects | |
| 120 ** pointed to by its arguments according to the format control | |
| 121 ** string. | |
| 122 ** | |
| 123 ** PR_sscanf() behaves the same way as the sscanf() function in the | |
| 124 ** Standard C Library (stdio.h), with the following exceptions: | |
| 125 ** - PR_sscanf() handles the NSPR integer and floating point types, | |
| 126 ** such as PRInt16, PRInt32, PRInt64, and PRFloat64, whereas | |
| 127 ** sscanf() handles the standard C types like short, int, long, | |
| 128 ** and double. | |
| 129 ** - PR_sscanf() has no multibyte character support, while sscanf() | |
| 130 ** does. | |
| 131 ** INPUTS: | |
| 132 ** const char *buf | |
| 133 ** a character string holding the input to scan | |
| 134 ** const char *fmt | |
| 135 ** the format control string for the conversions | |
| 136 ** ... | |
| 137 ** variable number of arguments, each of them is a pointer to | |
| 138 ** a data object in which the converted value will be stored | |
| 139 ** OUTPUTS: none | |
| 140 ** RETURNS: PRInt32 | |
| 141 ** The number of values converted and stored. | |
| 142 ** RESTRICTIONS: | |
| 143 ** Multibyte characters in 'buf' or 'fmt' are not allowed. | |
