RAND_load_file(3) -- PRNG seed file
|
|
RAND_file_name() generates a default path for the random seed file. buf points to a buffer of size num in which to store the filename. The seed file is $RANDFILE if that environment variable is set, $... |
|
rand_r(3) -- bad random number generator
|
|
These interfaces are obsoleted by random(3). The rand() function computes a sequence of pseudo-random integers in the range of 0 to RAND_MAX (as defined by the header file ). The srand() fun... |
|
RAND_set_rand_method(3) -- select RAND method
|
|
A RAND_METHOD specifies the functions that OpenSSL uses for random number generation. By modifying the method, alternative implementations such as hardware RNGs may be used. Initially, the default is ... |
|
rcmd(3) -- routines for returning a stream to a remote command
|
|
The rcmd() function is available for use by anyone to run commands on a remote system. It acts like the orcmd() command, with the exception that it makes a call out to the rcmd(1) command, or any othe... |
|
rcmd_af(3) -- routines for returning a stream to a remote command
|
|
The rcmd() function is available for use by anyone to run commands on a remote system. It acts like the orcmd() command, with the exception that it makes a call out to the rcmd(1) command, or any othe... |
|
readdir(3) -- directory operations
|
|
The opendir() function opens the directory named by filename, associates a directory stream with it and returns a pointer to be used to identify the directory stream in subsequent operations. The poin... |
|
realloc(3) -- general purpose memory allocation functions
|
|
The malloc() function allocates size bytes of memory. The allocated space is suitably aligned (after possible pointer coercion) for storage of any type of object. If the space is at least pagesize byt... |
|
realpath(3) -- returns the canonicalized absolute pathname
|
|
The realpath() function resolves all symbolic links, extra ``/'' characters and references to /./ and /../ in pathname, and copies the resulting absolute pathname into the memory referenced by resol... |
|
recno(3) -- record number database access method
|
|
The routine dbopen is the library interface to database files. One of the supported file formats is record number files. The general description of the database access methods is in dbopen(3), this ma... |
|
regcomp(3) -- regular-expression library
|
|
These routines implement IEEE Std 1003.2-1992 (``POSIX.2'') regular expressions (``RE''s); see re_format(7). regcomp() compiles an RE written as a string into an internal form, regexec() matches t... |
|
regerror(3) -- regular-expression library
|
|
These routines implement IEEE Std 1003.2-1992 (``POSIX.2'') regular expressions (``RE''s); see re_format(7). regcomp() compiles an RE written as a string into an internal form, regexec() matches t... |
|
regex(3) -- regular-expression library
|
|
These routines implement IEEE Std 1003.2-1992 (``POSIX.2'') regular expressions (``RE''s); see re_format(7). regcomp() compiles an RE written as a string into an internal form, regexec() matches t... |
|
regexec(3) -- regular-expression library
|
|
These routines implement IEEE Std 1003.2-1992 (``POSIX.2'') regular expressions (``RE''s); see re_format(7). regcomp() compiles an RE written as a string into an internal form, regexec() matches t... |
