HEXENCODE

HEXENCODE encodes a source buffer into a buffer holding its base 16 value in the character set specified by the ASCII or EBCDIC suboption of the DEFAULT compiler option. It returns a size_t value that indicates the number of bytes that are written into the target buffer.

p
Specifies the address of the target buffer.
m
Specifies the length in bytes of the target buffer. It must have a computational type and is converted to type size_t.
q
Specifies the address of the source buffer.
n
Specifies the length in bytes of the source buffer. It must have a computational type and is converted to type size_t.
The returned value depends on the address of the target buffer or the size of the target buffer:
  • If the address of the target buffer p is zero, the number of bytes that would be written is returned.
  • If the target buffer is not large enough, a value of -1 is returned.
  • If the target buffer is large enough, the number of bytes that are written to the buffer is returned.
Note: Some arguments or return values are of type size_t. If the LP(32) compiler option is in effect, size_t is FIXED BIN(31); if the LP(64) compiler option is in effect, size_t is FIXED BIN(63).
