atof (3)

#include <stdlib.h>

double atof(const char *nptr);

The atof() function converts the initial portion of the string pointed to by nptr to double. The behavior is the same as

strtod(nptr, NULL);

except that atof() does not detect errors.

The converted value.

Multithreading (see pthreads(7))

The atof() function is thread-safe with exceptions. It can be safely used in multithreaded applications, as long as setlocale(3) is not called to change the locale during its execution.
