XtCalloc() XtCalloc()
Name
XtCalloc - allocate memory for an array and initialize its bytes to zero.
Synopsis
char *XtCalloc(num, size);
Cardinal num;
Cardinal size;
Inputs
num Specifies the number of array elements to allocate.
size Specifies the size of an array element in bytes.
Returns
A pointer to allocated memory.
Description
XtCalloc() allocates memory for an array of num elements each of size bytes and initializes each allocated byte to zero. If there is
insufficient memory, XtCalloc() terminates by calling XtErrorMsg().
Usage
Note that in most cases, you will have to cast the return value of XtCalloc() to the type appropriate for the array elements you are allo-
cating.
XtNew() and XtNewString() provide slightly higher-level approaches to memory allocation.
The function XtCalloc() is implemented by the Toolkit independently of the particular environment, so programs ported to a system not sup-
porting calloc will still work.
