xt_malloc(3) Library Functions Manual xt_malloc(3) LIBRARY #include <xtend/mem.h> -lxtend SYNOPSIS void *xt_malloc(size_t nelem, size_t size) ARGUMENTS nelem: Number of objects to allocate size: Size of a single object DESCRIPTION xt_malloc() is a simple wrapper around malloc(3) that requires two ar- guments representing the number of objects to allocate and the size of an element. This prevents the very common mistake with malloc(3) of forgetting to multiply by the size of an element. Specifying the size using sizeof(*variable) has the advantage of being type-independent. I.e. if you change the type of the variable, this code need not be updated. Simply add one * to whatever the return value is assigned to. RETURN VALUES Address of the newly allocated array, or NULL if allocation failed EXAMPLES size_t widget_list_size = 1024; widget_t *widgets; widgets = xt_malloc(widget_list_size, sizeof(*widgets)); SEE ALSO malloc(3) xt_malloc(3)
