Dear Friends,
I want to create a hash table using the standard Glib header (if possible) so that I can store a structure and keep the hash key(search key) based on a string.
Any example code would be great since I am not able to get the main idea.
best regards

NICE(3P) POSIX Programmer's Manual NICE(3P)
PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond-
ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
NAME
nice - change the nice value of a process
SYNOPSIS
#include <unistd.h>
int nice(int incr);
DESCRIPTION
The nice() function shall add the value of incr to the nice value of the calling process. A process' nice value is a non-negative number
for which a more positive value shall result in less favorable scheduling.
A maximum nice value of 2*{NZERO}-1 and a minimum nice value of 0 shall be imposed by the system. Requests for values above or below these
limits shall result in the nice value being set to the corresponding limit. Only a process with appropriate privileges can lower the nice
value.
Calling the nice() function has no effect on the priority of processes or threads with policy SCHED_FIFO or SCHED_RR. The effect on pro-
cesses or threads with other scheduling policies is implementation-defined.
The nice value set with nice() shall be applied to the process. If the process is multi-threaded, the nice value shall affect all system
scope threads in the process.
As -1 is a permissible return value in a successful situation, an application wishing to check for error situations should set errno to 0,
then call nice(), and if it returns -1, check to see whether errno is non-zero.
RETURN VALUE
Upon successful completion, nice() shall return the new nice value -{NZERO}. Otherwise, -1 shall be returned, the process' nice value shall
not be changed, and errno shall be set to indicate the error.
ERRORS
The nice() function shall fail if:
EPERM The incr argument is negative and the calling process does not have appropriate privileges.
The following sections are informative.
EXAMPLES
Changing the Nice Value
The following example adds the value of the incr argument, -20, to the nice value of the calling process.
#include <unistd.h>
...
int incr = -20;
int ret;
ret = nice(incr);
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
None.
