Function Documentation

◆ xmalloc()

void* xmalloc ( size_t size )

Allocate size bytes on the heap.

This is a wrapper for malloc which calls panic() in case of errors, so no error handling is required for code using it.

◆ xrealloc()

void* xrealloc	(	void *	ptr,
		size_t	size
	)

Chane size of a previously allocated memory block to size bytes.

This is a wrapper for realloc which calls panic() in case of errors, so no error handling is required for code using it.

◆ xstrdup()

char* xstrdup ( const char * str )

Allocates memory and copies string str into it.

This is a wrapper for strdup which calls panic() in case of errors, so no error handling is required for code using it.
