Function Documentation

char* ccp4_utils_basename (  const char *    filename )

Extracts the basename from a full file name. Separators for directories and extensions are OS-specific. Parameters: filename  full file name string. Returns: pointer to basename

void* ccp4_utils_calloc (  size_t    nelem, size_t    elsize )

This is a wrapper for the calloc function, which adds some error trapping. Returns:

int ccp4_utils_chmod (  const char *    path, const char *    cmode )

Returns:

char* ccp4_utils_date (  char *    date )

Returns:

char* ccp4_utils_extension (  const char *    filename )

Extracts the extension from a full file name. Separators for directories and extensions are OS-specific. Parameters: filename  full file name string. Returns: pointer to extension

size_t ccp4_utils_flength (  char *    s, int    len )

Gets the length of a Fortran string with trailing blanks removed. Returns: length of string

void ccp4_utils_hgetlimits (  int *    IValueNotDet, float *    ValueNotDet )

Returns:

int ccp4_utils_isnan (  const union float_uint_uchar *    realnum )

Returns:

char* ccp4_utils_joinfilenames (  char *    dir, char *    file )

Joins a leading directory with a filename. Separators for directories and extensions are OS-specific. Parameters: dir  directory path. file  file name string. Returns: pointer to joined directory-filename path.

void* ccp4_utils_malloc (  size_t    size )

This is a wrapper for the malloc function, which adds some error trapping. Returns: void

int ccp4_utils_mkdir (  const char *    path, const char *    cmode )

Returns:

int ccp4_utils_noinpbuf (  void    )

Returns:

int ccp4_utils_outbuf (  void    )

Returns:

char* ccp4_utils_pathname (  const char *    filename )

Extracts the pathname from a full file name. Separators for directories and extensions are OS-specific. Parameters: filename  full file name string. Returns: pointer to pathname with trailing separator.

void ccp4_utils_print (  const char *    message )

Returns:

void* ccp4_utils_realloc (  void *    ptr, size_t    size )

This is a wrapper for the realloc function, which adds some error trapping. Returns:

int ccp4_utils_setenv (  char *    str )

Returns:

char* ccp4_utils_time (  char *    time )

Alternative to ccp4_utils_itime with time as character string. Parameters: time  Character string of form HH:MM:SS Returns: pointer to character string.

int ccp4_utils_translate_mode_float (  float *    out, const void *    buffer, int    dim, int    mode )

Returns:

char* ccp4_utils_username (  void    )

Return the user's login name. (MVisualStudio version in w32mvs.c) Note that getlogin only works for processes attached to a terminal (and hence won't work from the GUI). In these instances use getpwuid instead. Returns: pointer to character string containing login name.
