j0(3) -- Bessel functions
|
The j0() and j1() functions return Bessel functions of x of the first kind of orders 0 and 1, respectively. The jn() function returns the Bessel function of x of the first kind of order n. The y0() an... |
killpg(3) -- send signal to all members of a process group.
|
The killpg() function causes signal signal to be sent to all the processes in the process group pidgrp or to the processes' own process group if pidgrp is equal to zero. It is equivalent to kill(-pid... |
ldexp(3) -- multiply floating-point number by integral power of 2
|
The ldexp() function returns the result of multiplying the floatingpoint number x by 2 raised to the power exp. |
ldiv(3) -- computes the quotient and remainder of long integer division.
|
The ldiv() function computes the value numer/denom and returns the quotient and remainder in a structure named ldiv_t that contains two long integer members named quot and rem. |
lgamma(3) -- log gamma function
|
The lgamma() function returns the log of the absolute value of the Gamma function. The sign of the Gamma function is returned in the external integer signgam. For negative integer values of x, lgamma(... |
localeconv(3) -- get numeric formatting information
|
The localeconv() function returns a pointer to a struct lconv for the current locale. This structure is defined in the header-file locale.h and contains all values associated with the locale categorie... |
lockf(3) -- apply, test or remove a POSIX lock on an open file
|
Apply, test or remove a POSIX lock on an open file. The file is specified by fd. This call is just an interface for fcntl(2). Valid operations are given below: F_LOCK Set an exclusive lock to the file... |
longjmp(3) -- non-local jump to a saved stack context
|
longjmp() and setjmp() are useful for dealing with errors and interrupts encountered in a low-level subroutine of a program. longjmp() restores the environment saved by the last call of setjmp() with ... |
lrint(3) -- round to nearest integer
|
These functions round their argument to the nearest integer value, using the current rounding direction. If x is infinite or NaN, or if the rounded value is outside the range of the return type, the n... |
lround(3) -- round to nearest integer, away from zero
|
These functions round their argument to the nearest integer value, rounding away from zero, regardless of the current rounding direction. If x is infinite or NaN, or if the rounded value is outside th... |
lsearch(3) -- linear search of an array.
|
lfind() and lsearch() perform a linear search for key in the array base which has *nmemb elements of size bytes each. The comparison function referenced by compar is expected to have two arguments whi... |
malloc(3) -- Allocate and free dynamic memory
|
calloc() allocates memory for an array of nmemb elements of size bytes each and returns a pointer to the allocated memory. The memory is set to zero. malloc() allocates size bytes and returns a pointe... |
mblen(3) -- determine number of bytes in next multibyte character
|
If s is not a NULL pointer, the mblen function inspects at most n bytes of the multibyte string starting at s and extracts the next complete multibyte character. It uses a static anonymous shift state... |
