It allows a program to control multiple different flows of work that overlap in time. The <a href=\"..\/API\/\">API<\/a> is defined by the <a href=\"..\/IEEE\/\">IEEE<\/a> <a href=\"..\/POSIX.1c\/\">POSIX.1c<\/a> standard (IEEE Std 1003.1c-1995).<\/p><p>In the <a href=\"..\/C-programming-language\/\">C programming language<\/a>, <a href=\"..\/pthreads\/\">pthreads<\/a> are implemented as a library that provides functions for thread management, including creation, joining, and detaching. To ensure <a href=\"..\/Thread-Safety\/\">Thread Safety<\/a>, the library includes synchronization primitives such as <a href=\"..\/Mutex\/\">Mutex<\/a> (Mutual Exclusion) objects, <a href=\"..\/Condition-Variables\/\">Condition Variables<\/a>, and <a href=\"..\/Read-Write-Locks\/\">Read-Write Locks<\/a>. These tools are essential for preventing <a href=\"..\/Race-Conditions\/\">Race Conditions<\/a> when multiple threads access shared memory.<\/p><p>The <a href=\"..\/pthreads\/\">pthreads<\/a> library is standard on <a href=\"..\/Unix-like\/\">Unix-like<\/a> operating systems, such as <a href=\"..\/Linux\/\">Linux<\/a>, <a href=\"..\/BSD\/\">BSD<\/a>, and <a href=\"..\/macOS\/\">macOS<\/a>. When compiling applications using <a href=\"..\/GCC\/\">GCC<\/a> or <a href=\"..\/Clang\/\">Clang<\/a>, developers typically link the library using the <code>-lpthread<\/code> flag.
