43 ** API for PR printf like routines. Supports the following formats
45 ** %u - unsigned decimal
47 ** %X - unsigned uppercase hex
48 ** %o - unsigned octal
49 ** %hd, %hu, %hx, %hX, %ho - 16-bit versions of above
50 ** %ld, %lu, %lx, %lX, %lo - 32-bit versions of above
51 ** %lld, %llu, %llx, %llX, %llo - 64 bit versions of above
53 ** %hs - 16-bit version of above (only available if js_CStringsAreUTF8)
55 ** %hc - 16-bit version of above (only available if js_CStringsAreUTF8)
56 ** %p - pointer (deals with machine dependent pointer size)
67 ** sprintf into a fixed size buffer. Guarantees that a NUL is at the end
68 ** of the buffer. Returns the length of the written output, NOT including
69 ** the NUL, or (JSUint32)-1 if an error occurs.

75 ** buffer on success, NULL on failure. Call "JS_smprintf_free" to release
76 ** the memory returned.

87 ** the malloc'd buffer. sprintf will append data to the end of last,
88 ** growing it as necessary using realloc. If last is NULL, JS_sprintf_append
89 ** will allocate the initial string. The return value is the new value of
90 ** last for subsequent calls, or NULL if there is a malloc failure.

96 ** place into the output. "arg" is an opaque pointer used by the stuff
97 ** function to hold any state needed to do the storage of the output
98 ** data. The return value is a count of the number of characters fed to
99 ** the stuff function, or (JSUint32)-1 if an error occurs.

115 ** FUNCTION: JS_sscanf
117 ** JS_sscanf() scans the input character string, performs data
118 ** conversions, and stores the converted values in the data objects
119 ** pointed to by its arguments according to the format control
122 ** JS_sscanf() behaves the same way as the sscanf() function in the
123 ** Standard C Library (stdio.h), with the following exceptions:
124 ** - JS_sscanf() handles the NSPR integer and floating point types,
125 ** such as JSInt16, JSInt32, JSInt64, and JSFloat64, whereas
126 ** sscanf() handles the standard C types like short, int, long,
128 ** - JS_sscanf() has no multibyte character support, while sscanf()
132 ** a character string holding the input to scan
134 ** the format control string for the conversions
136 ** variable number of arguments, each of them is a pointer to
137 ** a data object in which the converted value will be stored
140 ** The number of values converted and stored.
142 ** Multibyte characters in 'buf' or 'fmt' are not allowed.
