_a2e_dup_n, _e2a_dup_n - Convert from ASCII to EBCDIC and EBCDIC to ASCII

Definition	#include <ascii_ebcdic.h> char*_a2e_dup_n (const char* z, size_t n); char*_e2a_dup_n (const char* z, size_t n); The functions _a2e_dup_n and _e2a_dup_n create a new string by taking z and converting precisely n characters from ASCII to EBCDIC and vice versa. The memory for the new string is allocated by means of malloc(), and it is up to the user to release it. If the available memory is insufficient, NULL is returned as the result. Otherwise, the new, nullterminated string is returned. The conversion tables are declared as follows: unsigned char _a2e_tab[256]; unsigned char _e2a_tab[256];
Parameters	char* z String in ASCII or EBCDIC encoding to be converted size_t n Number of characters to be converted in the string z
Return val.	New EBCDIC or ASCII string (if successful) NULL, if there is insufficient memory
Note	These functions are suitable for processing character arrays containing the null byte (\0), since they do not interpret the null byte as the ’end of text’.
