mem_set¶
mem_set sets the bytes in a string to values of a specified data type.
- bool = mem_set(ssString, pos, values, ssType)
Return Value
bool is TRUE (1), if the function was executed successfully and otherwise FALSE (1).
Parameters
- ssString
ssString is a string with sufficient space to contain
len(values)of ssType data type.
- pos
pos is the position in the string (>= 1).
- values
values are the values which are written to the string.
- ssType
ssType is the data type. List of data types:
Typ
Description
“int8” or “char”
One signed byte (-127 bis 127). values can be a real vector or a string.
“wchar_t”
UTF-16 Unicode character (2 bytes). values can be a real vector or a string.
“uint8” or “uchar”
One unsigned byte (0 bis 255).
“int16”
16-bit integer (2 bytes).
“uint16”
16-bit unsigned integer (2 bytes).
“int32”
32-bit integer (4 bytes).
“uint32”
32-bit unsigned integer (4 bytes).
“int64”
64-bit integer (8 bytes). Because UniScript stores 64-bit integers in double format, only (approx.) 52 bits are valid.
“uint64”
64-bit unsigned integer (8 bytes). Because UniScript stores 64-bit integers in double format, only (approx.) 52 bits are valid.
“float”
32-bit real values (4 bytes).
“double”
64-bit real values (8 bytes).
Example
// Create string with 40 Bytes.
v = mem_alloc(40);
// Write 10 integer values into the buffer (1 .. 10).
mem_set(v, 1, 1:10, "int32");
// Read the 10 values
res = mem_get(v, 1, "int32", 10);
