|
|
ctermid() returns a string which is the pathname for the current controlling terminal for this process. If s is NULL, a static buffer is used, otherwise s points to a buffer used to hold the terminal ... |
|
ctime(3) -- transform binary date and time to ASCII
|
|
The ctime(), gmtime() and localtime() functions all take an argument of data type time_t which represents calendar time. When interpreted as an absolute time value, it represents the number of seconds... |

cutbuffer(3) -- Manipulate X cut buffer properties
|
|
The cutbuffer command allows you to read or modify the eight X cut buffer properties. You can also rotate the buffers properties. |
|
daemon(3) -- run in the background

These functions generate pseudo-random numbers using the linear congruential algorithm and 48-bit integer arithmetic. The drand48() and erand48() functions return non-negative double-precision floatin... |
|
drem(3) -- floating-point remainder function
|
|
The drem() function computes the remainder of dividing x by y. The return value is x - n * y, where n is the quotient of x / y, rounded to the nearest integer. If the quotient is 1/2, it is rounded to... |
