** FUNCTION: PR_sscanf
|
|
** DESCRIPTION:
|
|
** PR_sscanf() scans the input character string, performs data
|
|
** conversions, and stores the converted values in the data objects
|
|
** pointed to by its arguments according to the format control
|
|
** string.
|
|
**
|
|
** PR_sscanf() behaves the same way as the sscanf() function in the
|
|
** Standard C Library (stdio.h), with the following exceptions:
|
|
** - PR_sscanf() handles the NSPR integer and floating point types,
|
|
** such as PRInt16, PRInt32, PRInt64, and PRFloat64, whereas
|
|
** sscanf() handles the standard C types like short, int, long,
|
|
** and double.
|
|
** - PR_sscanf() has no multibyte character support, while sscanf()
|
|
** does.
|
|
** INPUTS:
|
|
** const char *buf
|
|
** a character string holding the input to scan
|
|
** const char *fmt
|
|
** the format control string for the conversions
|
|
** ...
|
|
** variable number of arguments, each of them is a pointer to
|
|
** a data object in which the converted value will be stored
|
|
** OUTPUTS: none
|
|
** RETURNS: PRInt32
|
|
** The number of values converted and stored.
|
|
** RESTRICTIONS:
|
|
** Multibyte characters in 'buf' or 'fmt' are not allowed.
