char *strerror(int errnum);

Description

Returns a pointer to an error message string.

strerror takes an int parameter errnum, an error number, and returns a pointer to an error message string associated with errnum.

Return Value

strerror returns a pointer to a constructed error string. The error message string is constructed in a static buffer that is overwritten with each call to strerror.

Example

 #include <stdio.h>
 #include <errno.h>
 int main(void)
 {
   char *buffer;
   buffer = strerror(errno);
   printf("Error: %s\n", buffer);
   return 0;
 }
