Detailed Description

This is wrapper code around gnulib's srandom_r() and random_r() with automatic seeding

Function Documentation

◆ wget_random_init()

void wget_random_init ( void  )

Random API initialization, allocating/preparing the internal resources.

On systems with automatic library constructors, this function doesn't have to be called explicitly.

This function is not thread-safe.

◆ wget_random_exit()

void wget_random_exit ( void  )

Random API deinitialization, free'ing all internal resources.

On systems with automatic library destructors, this function doesn't have to be called explicitly.

This function is not thread-safe.

◆ wget_random()

int wget_random ( void  )
Returns
Random value between 0 and RAND_MAX

This functions wraps around gnulib's random_r(). It performs a thread-safe seeding on the first use, if not done before by wget_srandom();

◆ wget_srandom()

void wget_srandom ( unsigned int  seed)
Parameters
[in]seedValue to seed the random generator

This functions wraps around srandom_r() to make a thread-safe seeding for wget_random().
