#include <cfht/cfht.h>char *cfht_toe(src, dest, size)char *src;char dest;int size; libcfht.a
Src is the source string, and dest is a place to put the created string. Since there may be nulls in the source string, size may be passed in as a counter for examining the source string. 0 may be used for size, in which case conversion will proceed to the first null. This feature should not be used unless it is known that there will be no nulls in the string except at the end.
The src and dest pointers must be non-NULL, and the space for the dest characters must already exist. Src and dest should not be set to the same or overlapping values.
Any non-printable character as defined by isprint(3C) will be converted to a \ followed by three octal digits. The destination string will be null terminated.
