getwd(3) Library Functions Manual getwd(3) NAME
getwd - Gets current directory pathname LIBRARY
Standard C Library (libc.so, libc.a) SYNOPSIS
#include <unistd.h> char *getwd( char *path_name); STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: getwd(): XPG4-UNIX Refer to the standards(5) reference page for more information about industry standards and associated tags. PARAMETERS
Points to the full pathname. DESCRIPTION
The getwd() function determines the absolute pathname of the current directory, then copies that pathname into the array pointed to by the path_name parameter. The maximum pathname length, in characters, is set by the PATH_MAX definition, as specified in the limits.h file. If the length of the pathname of the current directory is greater than (PATH_MAX + 1), including the null byte, getwd() fails and returns a null pointer. RETURN VALUES
Upon successful completion, a pointer to the absolute pathname of the current directory is returned. If an error occurs, the getwd() func- tion returns a null pointer. and places a message in the path_name parameter. RELATED INFORMATION

getwd - get current working directory pathname SYNOPSIS
#include <unistd.h> char *getwd(char *path_name); DESCRIPTION
The getwd() function determines an absolute pathname of the current working directory of the calling process, and copies that pathname into the array pointed to by the path_name argument. If the length of the pathname of the current working directory is greater than (PATH_MAX + 1) including the null byte, getwd() fails and returns a null pointer. RETURN VALUES
Upon successful completion, a pointer to the string containing the absolute pathname of the current working directory is returned. Other- wise, getwd() returns a null pointer and the contents of the array pointed to by path_name are undefined. ERRORS
No errors are defined. USAGE
For portability to implementations conforming to versions of the X/Open Portability Guide prior to SUS, getcwd(3C) is preferred over this function. ATTRIBUTES
