|BIO_DUMP(3)||Library Functions Manual||BIO_DUMP(3)|
hexadecimal printout of arbitrary byte arrays
BIO_dump(BIO *b, const char *s, int len); int
BIO_dump_indent(BIO *b, const char *s, int len, int indent); int
BIO_dump_fp(FILE *fp, const char *s, int len); int
BIO_dump_indent_fp(FILE *fp, const char *s, int len, int indent);
BIO_dump() prints len bytes starting at s to bio in hexadecimal format. The first column of output contains the index, in the byte array starting at s, of the first byte shown on the respective output line, expressed as a four-digit hexadecimal number starting at 0000, followed by a dash. After the dash, sixteen bytes of data are printed as two-digit hexadecimal numbers, respecting the order in which they appear in the array s. Another dash is printed after the eighth column. To the right of the hexadecimal representation of the bytes, the same bytes are printed again, this time as ASCII characters. Non-printable ASCII characters are replaced with dots. Trailing space characters and NUL bytes are omitted from the main table. If there are any, an additional line is printed, consisting of the len argument as a four-digit hexadecimal number, a dash, and the fixed string “<SPACES/NULS>”.
BIO_dump_indent() is similar except that indent space characters are prepended to each output line. If indent is 7 or more, the number of data columns is reduced such that the total width of the output does not exceed 79 characters per line.
BIO_dump_indent_fp() are similar except that fwrite(3) is used instead of BIO_write(3). BIO_write(3) or fwrite(3). If a failure occurs at any point when writing, these functions will stop after having potentially written out partial results, and return -1. hexdump(1), BIO_new(3), BIO_write(3)
